I admire Tim Burton's vision even in the movies I feel are unsucessful. Batman Returns is a better movie than the first one, but he took the wrong approach with the Penguin by making him a grotesque. I actually liked his take on Catwoman. And Michael Gough's performance as Alfred was simply wonderful. After seeing Jim Carrey as the Riddler I wished he had been cast as the Joker. He had the lanky loony look down perfect.
All the same, I think Burton's best movies are the ones that are animated. There he can indulge in his amazing visions without it being too jarring, as it usually is in his live action films. The only live action movie of his I thought was almost perfect was Ed Wood, and in there the visuals were played down.
