I haven't seen the film but based on the trailers I think Allen is dead on in his observation that it's not really Buzz the toy. It's some guy in a star wars sort of setting. If it was a movie about the Buzz Lightyear character as it always has been it would be some goofy old style Flash Gordon kind of thing with crazy aliens and silly cartoonish hijinx with a clueless but overly courageous and loyal Buzz at the center of it all. In other words, no message telling us to do better, just a bit of fun.
How can they be surprised after making a movie named after a character that people love but having him be totally different would be unwelcomed by those fans?
