Yeah, but Polanski had a flair-up in the news this year. I think that may have worked against him. Of course, the fact that it was released sometime before Christmas 2010 makes it typically ineligible for a 2010 Oscar.
Inception is a big exception to this rule. I, too, really don't care to see it again. It didn't hold up so well on the 2nd viewing. But there was no other film this year that inspired so much conjecture and conversation and philosophical flights of fancy, at least for me. So I continue to hold it in very high regard.
I admire Tron for being one of those films where, apparently, you either like it or hate it - even though I'm on the hate-it side. I expected the story to be stupid, but not nearly as stupid and unforgivably DULL as it was. And to my surprise, the costumes were meh (so inferior to the first film) and the much vaunted score by Daft Punk was typical and boring when it wasn't in their better mode of electronica (which it wasn't for most of the film). So while I went in with low expectations, the movie -er - exceeded them on the downside.
BUT - I love the Tron disc I got for Christmas - so I'll give points to the merchandise offshoots. Oh, and the lightcycle race was rad.
