American Beauty - hokey sentimentality, though I like Kevin Spacey's performance.
Black Swan - rubbish.
Inception - a solidly good movie with some great visual elements and some flaws (e.g. too much exposition, a middling DiCaprio performance) that don't detract too much.
Funny Games - I've seen bits and pieces of at least one (possibly both) versions. I find the idea interesting but am unlikely to ever sit down and watch it.
Citizen Kane - I saw it as a teenager, probably before I knew enough about film to appreciate it, and liked but didn't love it. Should probably watch it again sometime.
Matchpoint - you mean the Woody Allen one? Rubbish. As far as his mid-oughts London-set films with Scarlett Johansson, Scoop is a million times better.
