Burton should stay far, far away from Wizard of Oz and Peter Pan. The last thing we need a Oz or Pan being about emo (oh God, did I just type that horrible word) outsiders. Wizard of Oz is fun because its odd, but its not out and out nightmarish like Burton would want it. Same goes for Peter Pan. We've already seen what a filmmaker departing from the source material will do it with Hook. Heaven knows we don't need a repeat of that aborted attrocity.
Also, his adaptation of Sweeney Todd sucked. He cut all of the other themes not pertaining to lonesome outsiders like Todd out, over-simplified Anthony and Johanna's romance, and ruined the music.
Then before that, Corpse Bride was lackluster.
Then before that, what he did with Charlie and the chocolate Factory was unforgiveable. In a single moment, Wonka trying to take Charlie from his family ruined the entire film for me. Not to mention that the subplot with Wonka's father was completely unneeded, as were all the other things he added. I also found Charlie to be way over the top in how squeaky clean wholesome he was. At least the old Charlie from the Gene Wilder version acted like a kid. He was a good kid, but not perfect.
Big Fish was his last truly great film.
