I was nonplussed by this movie. Granted, I missed the last 10 minutes because Clark wisely decided it was time to go. (This is a great way to beat traffic, by the way: Just skip the last 10 minutes of the movie. Few others think of this clever strategy.)
Notwithstanding my incomplete viewing, I don't understand why Tyler Cowen likes this movie so much. (Then again, he has a crush on Will Wilkinson; if I knew Latin I'd put in that famous phrase about no accounting for tastes.)
Don't get me wrong, Pixar is awesome; within 10 minutes you are rooting for the little guy. But other than that, I think the message was wrong. Sure, Westerners are lazy and overweight and there are problems with commercialism. (Incidentally, why does Tyler Cowen of all people like this movie?!) But I really don't think we are destroying the earth. I don't endorse his unmerciful tone, but I think my former student makes some good points--especially at the end when he says that he's seen firsthand what a lack of capitalism looks like.
Also, just a minor quibble, but there's no sound in space! Only the people involved in 2001 and 2010 had the courage to do this right.
