Well, if it was unintentional, then I just may look at it with an mor eopen mind. I just didn't like the feeling that I was being preached to, especially over something I see everywhere I go, literally. I also care about the environment, but geez, all those "save the flora and fauna!" treehuggers get annoying after a while!
Anyway, back to topic, I liked the film overall, but I much prefered the Toy Story movies, A Bug's Life, The Incredibles, and Meet the Robinsons to Wall-E.
My favorite two characters were Wall-E and "Eve-a". There interactions were SO hilarious and they were so comedically mismatched that their scenes were just to die for.
