Eh, I didn't really expect
Trek to be nominated for Best Picture... although it would have been nice.

Still, it did get four nominations, and technical or not, that's recognition from the Academy, which ain't a bad thing.
Not too surprised about
Avatar; a little surprised about
District 9. I enjoyed both films, although I did think they both had their flaws. Of course, I could say the same about
Star Trek (which I did
enjoy more than the other two... but I'm probably biased.

I'd be hard-pressed to say objectively which of the films is best). I think I can kind of see why the Academy would deem
Avatar and
District 9 more "award-worthy", though. In any event, I am rather delighted to see a strong sci-fi presence in the Best Picture category.
I haven't seen
The Blind Side (just not really interested), but... really? Is it actually that good? Like I said, I haven't seen it, but it gave me the impression it was just your average "feel-good, root-for-the-underdog" sports movie. I feel like it might be on the list purely for its surprising popularity with audiences.
