I liked both of them but neither are my favorites. If I had to choose, I would choose TDK though. I got Wall-E and I will probably watch it again with my kids, but I think The Incredibles, Cars & Monsters Inc were all better films.
Nice post, goosehorn. I think some of your criticism about The Dark Knight is right on. It is a little too busy and I'm not crazy about the tired trick of is he dead or isn't he. Ledger was great and the movie seems to be hunting bigger game than just a simple good guy bad guy story.
I didn't get out of Wall-E what you did, but so it goes.
