Toss up between Inglourious Basterds and The Matrix
Inglorious Basterds because it felt like the result of someone with a very shaky grasp of history wanking onto some celluloid. Which is weird because its clearly very well researched (the German bar scene, for example). I think, ultimately, its because I didn't like the Basterds. Other than feeling entirely superfluous, serving little apparent purpose other than to mess up everyone else's plans, they have the unfortunate "America! Fuck yeah!" aura about them which I really thought you'd outgrown. I mean, they stroll into a theatre crawling with Nazi higher-ups with no disguises, no ability to speak German (or Italian, since that was their cover) and the only one to spot them is the guy who already knows they're coming? Then there's the film's message that War Is Bad, seen mostly the German sniper who can't watch the film of him shooting other people. Oh, but here come the Basterds and look at how funny it is to see them beat someone to death with a baseball bat! And that sniper turns out to be an asshole too, as though the movie realised its protagonists were unlikable halfwits so had to compensate by chucking a would-be rapist in there as antagonist. I feel the movie would have been better overall if they'd been cut out and it had just been about the French cinema owner and her quest to strike back using the power of film.
The Matrix I lean more towards indifference than dislike, but I think it has a few problems. other than the sequels I mean. For a start, its not quite as clever as it thinks it is. You can quote and reference Alice in Wonderland as much as you like, that doesn't make you deep. And there is pretty much no characterisation going on. Keanu Reeves is just Keanu Reeves, Trinity is much the same (her "I love you" bit at the end is totally without emotion, it might as well be two planks of wood kissing each other), Morpheus is a walking cut-out...About the only actual characters I can think of are Mouse and Agent Smith. So it really galls me when a whole bunch of the heroes are killed off in a single scene and they expect me to care. I can't even remember their names, for crying out loud. And I'm not getting any sorrow from the survivors, so I guess they don't either.
Oh, and how is Traitor Guy (nope, can't remember his name either) able to leap into the Matrix unassisted? He has that scene where he waxes lyrical over steak with Agent Smith and all I could think was "wait, how did he get there? if he's there, his real body must be in one of those machines the good guys have. Do they not think its odd he'd want to go into the Matrix alone? They seemed to have some way of tracking people's progress inside the virtual world before, do they not wonder why he's just been sitting in one place for ages?"
