Okay, I'll play:
-The Last Airbender: I like this film. Yes, FILM. As in, the one created by M. Night Shamyalan (spelling?) that was one of the worst received movies of...well, maybe not all time, but you know what I mean. Like the cartoon much more though.
-Avatar: The James Cameron film. IMO, an amazing movie, in terms of visuals, characters/characterization, storytelling, and themes. Has it been done before? Yes. Does that diminish it as a film? No.
-Battlefield Earth: I...actually like this film. Like the Last Airbender, I can watch a review tear it apart and agree with pretty much every point, but...well, sorry, I still like it. And not entirely in a guilty pleasure sort of way.
-Cars: I like this film. Actually, more than a few other Pixar films. On the flipside, my least favorite Pixar film is Cars 2, so there's that.
-DC Films: Man of Steel isn't terrible. It's okay. Flawed, but honestly, I still like it. Conceptually, thematically, honestly, even aesthetically. IMO, the main problem the film had was its pacing.
-Elysium: I don't know if this is an unpopular opinion, but I'll say this - this film is nowhere near as intelligent as it thinks it is. It's an action movie with some interesting ideas that feel...compressed, somehow. But either way, they never get to the surface, as the action takes over.
-Ender's Game: Is it controversial to say I liked this film? I dunno. But yes, I like this film. I think it's good. Not as good as the book, but a well done adaptation of it, and is entertaining in its own right.
-Frozen: This film is good. It's not overrated. Overhyped, maybe, but overrated? Nup. IMO, a genuinely good film, and would easily be among my top Disney animated films.
-Gravity: One of the greatest sci-fi films ever made. One of the few films I've seen in theatres that goes beyond film, but is an experience. There, I said it!
-Harry Potter: Not sure is this is controversial or not, but I'll say this - the books are much better than all the film adaptations, most of which are, IMO, "okay." I feel the only exceptions are Order of the Phoenix and Deathly Hallows pt. 2. And if anything, Prisoner of Azkaban was when the films started to lose something for me.
-Incredibles: I think this film is okay. Not bad, not good, not okay. Heck, I honestly like Cars more.
-Interstellar: Poor dialogue, poor characters, and a plot that falls apart under scrutiny. Honestly, I dislike this film more than I should, admittedly. But I can take a bad movie. But what's worse than a bad movie is a bad movie that thinks it's profound, when it just fails miserably at being so.
-James Bond: Um...is it controversial to say that Craig is my favorite Bond, that GoldenEye, Skyfall, and Casino Royale take the no. 3, 2, and 1 spots on my favorite Bond films, and that Connery is my second least favorite Bond actor? Well, there you go.
-Jupiter Ascending: I...kinda like this film. Oh, it's not a good one. Its protagonist has no arc, the script is a mess, and it feels a lot like what people accused the Phantom Menace of being - a pseudo space adventure filled with politics. And yet, I kinda like it. But more in the sense of that I feel it could have been so much more, if it had a tighter script and better character arc.
-Jurassic Park: Is it popular to say I liked Jurassic World, or disliked it? No idea any more. Well, being honest, I liked it. Not as much as JP1/2 (yes, I like 2), but still enjoyable. Good action, fun, if not deep characters, and...well, it has a theme, I'd argue. Heck, I'd argue that even JP3 has a theme. Not a deep theme in this case, but still there. So, overall, fun time, but still a popcorn flick.
-The Hobbit: I think the films are good. Flawed, nowhere near the level of the LotR trilogy, but still good. Enjoyable. Fun. Films I enjoyed for what they were.
-Matrix: The Matrix Reloaded is a good film that doesn't reach the heights of the first, but still resides in "good," if not "excellent" territory. I'd even argue no. 3 is "okay," albeit still the weakest of the trilogy.
-Marvel: Okay, this needs a list of its own. But on that note:
-Spider-Man 3 isn't a bad film. Easily the weakest of the Rami trilogy, but not bad. I can still enjoy it overall.
-The first two Fantastic Four movies are "meh." Not terrible, just "meh."
-The only MCU films I've enjoyed are Guardians of the Galaxy, Iron Man 1, and Iron Man 3. And 3 would be my favorite.
-Of the X-Men movies, I like X-Men 3. More than the first two. First Class remains my favorite though.
-Mission: Impossible: I liked MI2 more than MI1 back in the day. No idea if this is still true, but hey, tossing it in.
-Mortal Kombat: Average, but enjoyable. Probably one of the best videogame movie adaptations out there. Sad, isn't it?
-Oblivion: A better film than many give it credit for. Primarily action, but good characters, good visuals, honestly, even well integrated themes and ideas as well.
-Over the Hedge: If asked what are Dreamworks' best hits, I'd point to Shrek and How to Train Your Dragon (liked Antz and Prince of Egypt, but I don't think that's too rare). However, this is a little gem for me in their library that I still quite like.
-Pirates of the Caribbean: This might not be too controversial, but IMO, the franchise is a case of where each film is worse than the one preceeding it. That said, I do enjoy the second film quite a bit as well. To me, it was 3, not 2, that really set the film series down on a spiral.
-Prince of Persia: The best videogame film ever made...which isn't saying that much admittedly. But hey, it's a fun popcorn flick. Likable characters. No idea how faithful it is. But honestly, I feel this is much underrated when MK is labeled as the best such adaptation. MK, IMO, relies on knowledge of the game to actually appreciate, and even then in a campy sense. PoP, on the other hand, stands on its own, and IMO, does so quite well.
-Resident Evil: The first film is...actually okay, to be honest. I give the series a lot of flak, especially no. 5 (which I saw this year...oh God...), but, in fairness, I think it started off...well, better than how it's so far ended, to be honest. Heck, I even enjoyed the second, and could appreciate elements of no. 3. But like PotC, I think this series is another case of each installment being worse than the one before it.
-Small Soldiers: I admit, this is pure nostalgia. But yes, I loved this movie as a kid. It's been pointed as an aping of other films (Gremlins, Toy Story), but yes, I still liked it.
-Space Odyssey: Yes, I can admit, 2001 is a landmark in cinema. From a visual and thematic standpoint, it's brilliant. However, I don't like watching it, and that can mainly be boiled down to its pace. Honestly, I think Blade Runner is a better example of visuals enriching a story that's also thematic, that also deals with questions of existentialism. So, yes. I can appreciate it as a landmark. But it's not a film I enjoy watching.
On the flipside, I love 2010. Got its themes, ideas, characters, etc. While it's often looked over in favor of its Kubrickian counterpart, IMO, this film needs more love.
-Star Trek: I like the Abrams movies. Deal with it. Yes, they were my first proper entry to Star Trek. Since then, my favorite Star Trek era so far is TNG. Yes, you can say "I was a Star Trek fan long before you were." But...well, sorry, I still think they're good films, and that Into Darkness is even better than STXI.
Oh, and First Contact is my favorite Star Trek film. Wrath of Khan takes the no. 2 spot. Heresy, I know.
-Starship Troopers: The second and third films are still fun. They don't hold a candle to no. 1, but I still like them. Mostly. Even if no. 2 gets WEIRD...0_0
-Star Wars: I'll leave this here as my personal worst to best list:
6) Attack of the Clones
5) The Phantom Menace
4) The Empire Strikes Back
3) Revenge of the Sith
2) Return of the Jedi
1) A New Hope
On that note, I don't think the prequels are bad, just flawed, and that's not including Revenge of the Sith. On, and Return of the Jedi is my favorite, though in all honesty, I think A New Hope is the better crafted film, hence its positioning.
-Terminator: I rank these films as T2>T1>T5>T4>T3. Honestly, I think T4 is woefully underrated. And T3 isn't even bad, just lacklusture, and an aping of T2, and a...well, yeah. I don't think T3 is "bad," but I still dislike it immensely. But, of that list, I think Salvation and Genisys need more love.
-Titan A.E.: I have weird feelings on this. Many say it's underappreciated. To be honest, I'm not sure if it is. Because I think this is a case of where the novelization actually does better than the film, at least in regards to fleshing out character, and more importantly, the drej. In the film, a lot of motivations are left iffy, and the setting pretty vague. So, yeah. If you love the film, great. But if you do so, I reccomend picking up the novelization as well. As someone who still likes this film, it made for an interesting read.
-Total Recall: The remake is good. Almost as good as the original. Feels different, looks different, heck, does better in some areas.
-Toy Story: TS1>TS3>TS2. Yes, I think TS2 is the weak link in the trilogy. Deal with it.
-Treasure Planet: A good, fun adventure. Not one of Disney's best, but hardly one of their worst either.
-Tron: I like Tron: Legacy more than the original. Both are flawed, both do things well, both are actually rather different in their approach. But at the end of the day, I like the sequel more.
-WALL-E: The best Pixar film ever made. Deal with it.
-War of the Worlds: The Spielberg film. Flawed, yes, especially in its third act. I'd argue that the moment we see the aliens is the moment the film loses its "oomph." But, IMO, vastly underrated overall.
-Alien 3: One of the most criminally underrated movies out there IMO. Not as good as 1 or 2. But still "good," in my mind. IMO, Alien 3 is the end of a solid trilogy (not counting Resurrection in that analogy).
-The Martian: I liked the film. I found it "okay." However, I think the book is much better, and, while it was a step up from Prometheus, it's a long way from being in the league of Alien and Blade Runner.
So, yeah. Honestly, I'm reminded of Good Bad Flicks, in that it seems most of these deviations are "I like it more than others" rather than "I dislike it more than others." Anyway, that's just a few.
Using the broadest definition of "few," that is. 0_0
