The dude had a hell of an amazing run for a while there, Pee Wee's Big Adventure, Beetlejuice, Batman, Edward Scissorhands, Batman Returns and Ed Wood are all great movies, but then I guess he kind of said all he really needed to say and quickly became self parody.
For me the end of classic era Burton is Mars Attacks, which is a mixed bag and I can forgive some people for not liking it, though for me personally I've always really liked that movie, but that was the last time I felt like he still had a certain "spark" to his movies and it's been mediocre to flat out bad ever since.
He had an amazing run but you also have to consider the time he had that run in. All 80s and early 90s stuff and that culture would absolutely not fly today.
