The fact that he himself still has anything to do with determining the flow and popularity of new films. Seriously, the man is artistic poison. I used to like his reviews until I realized he gives 4 out of 5 big-budget films an automatic pass; it takes something as awful as the Transformers sequels to drag an F rating out of him. Roger Ebert reviews are the film equivalent of payola, I'm almost certain of it. I'm not saying he needs to be a pretentious, judgmental ass, but seriously: can he even remember back to the time when he had standards?
And that whole vintage review thing? I get that it's cute when video game magazines or music rags do it, but they make it a weird little back page bit - often with some self-mockery thrown in there. I continue seeing dead serious reviews of things like Gone With The Wind when I look up his work. News flash, Bob: even you, old and outdated as you are, were still egg #37 back up in your mom's ovaries when Gone with The Wind came out. Yes, the Wizard of Oz, too. Quit spewing your bullshit about old movies; we don't care.
And speaking of video games, I'm sure you've all read plenty about his pretentious screed(s) that video games are not, and can never be, an art form. If the jackass was born 40 years earlier I'm sure he'd have said the same thing about film. He looks at passing media coverage of crap like Saints Row, chooses to consider that the apex of the art form, and concludes it will never be Art at all. Never mind that Saints Row, Streets of Rage, or Halo are our equivalent to Chris Tucker movies: no one ever said those were high art, they're just mindless fun.
Anyway, I should probably stop validating him with so much attention. He's a self-involved tool with no sense of perspective or irony whatsoever, he can't critique his way out a paper bag these days, and hopefully he'll retire soon.
