Though I don't really see "The Artist" mentioned often in any capacity, I think it'll be remembered as more of a bizarro one-off due to its format, release date and lack of star power rather than being unworthy of the award, let alone an "actively bad film".
I sort of agree on "Crash" as well but I barely remember it so I can't be sure. Still, like "American Beauty" it seems to get more shit on Babble than it really deserves.
I tend to gravitate towards weird stuff myself but still found "Birdman" pretty disappointing. Like most PT Anderson films, it proves the importance of a good script. All the other ingredients are there (interesting/unique concept, solid performances, cool visual style and like Anderson's films, it even has a extraordinary soundtrack) but for a film that relies so much on its dialogue, the dialogue is surprisingly weak.
I always sort of forget about "LA Confidential" and should probably rewatch it. And it seems like *most* folks have basically forgotten it because you never hear it mentioned anymore so I'd agree that while it's undoubtedly a better film than "Titanic" (though I seem to like that film more than most Babblers), it's probably not as "significant".
