Premiere: Politics can teach movie studios a lot about marketing. If someone isn't buying what you're selling, simply brand 'em unpatriotic! Or socialist! Or Hitler!
That's the intolerance of intolerance, and nowhere is it more prevalent than in peoples' tastes in film. Suggest that Gandhi is too long and you're a monster. Call United 93 pandering and you hate America. With Important Movies, dissent is tantamount to treason, so you have to like them.
