Academy Awards doesn't mean much to me. Usually it's popularity or the more "political correct" winners.
Anyways, I'm not saying Fincher is a bad director or anything like that, obviously he's very talented. I just think recently he's been a bit overrated, especially with the social network (personally, again my opinion, I honestly didn't think it was a great movie at all). Talented, absolutely. Good at what he does? He's great. Just a bit overrated imo. Se7en & Fight Club were fantastic films. Everything since, in my mind, has been pretty average.
What he's really good at is signing on to projects that are really interesting and are typically different stories than what we're used to.
