Tim Burton might well be the most overrrated director for all I care. Don't get me wrong, I've watched most of his movies and even appreciated some but I won't be your regular fanboy saying that ALL his movies are great.
Sweeney Todd was just so boring. I don't even mind it was a musical because I certainly appreciated that but the script was just a disaster. Everything was so readable from the start and nothing there quite surprised me.
The two movies which I believe are his best are
Sleepy Hollow and Mars Attacks! And I also kind of fell for The
Nightmare Before Christmas but most likely because it's got a great soundtrack.
Planet Of The Apes was your typical Hollywood movie with nothing to expect from
Charlie and... was a visual
Nightmare and most kids there that played in I wanted to slay with a rusty
Chainsaw Edward Scissorshands is just barely watchable...
And so on...
