I didn’t see a lot of movies in 2009 (Inglourious Basterds, District 9, Watchmen, Burma VJ, The Informant, Star Trek) so putting Up In the Air at the top of the list belies how good I thought the movie was. Watching the people get fired was disturbing. I know they were actors but, watching them, it was easy to imagine my butt in that chair.
If you do a lot of flying in your job, this movie will speak to you. One way, or the other.
PS: Have not seen Avatar
