Alright:
-Beauty and the Beast (it's good, but I don't think it deserves the pedastal that so many put it on. Even compared to other Disney Renaissance films, I'd rank it below Aladdin and Lion King)
-Ghostbusters (similarly, I think it's a good movie, but I don't think it's the Second Coming of Zuul...it's just a good fun movie. That's it.)
-Henry V (1944): Haven't seen too much of this, but of what I have seen, it pales in comparison to the 1989 version)
-Doctor No/From Russia with Love (while Connery had at least one good James Bond film with Goldfinger, these films...I don't get why they're so loved. Doesn't help that Connery is my second least favorite version of Bond)
-Men in Black (similar to Ghostbusters - it's a fun, good movie, I just don't get why it was apparently so good to launch the franchise it did)
-The Mighty Ducks (about the most cliched children's sport film you can imagine. Doesn't help that Little Giants came out two years later and, while having a similar premise, executes it much better)
-2001: A Space Odyssey (I can appreciate this film's influence within the genre, but it doesn't change the fact that it's a chore to sit through, and a pale imitation of the book it's based on)
-Star Trek IV: The Voyage Home (not the worst Star Trek movie, but I really dislike it, and that isn't helped by the fact that so many people love this installment)
-Star Wars: The Empire Strikes Back (always considered it to be the weak link in the original trilogy)
-Teenage Mutant Ninja Turtles (1990) (this...isn't a good film. Maybe the more recent ones are indeed worse, but this one is by no means "good")
-Toy Story 2 (this is okay, but it baffles me that it's so highly regarded, especially in comparison to Toy Story 1/3)
-Tron (the film tries, but its effects have aged terribly, and its characters and writing are really wonky.)
