Well, it has a great cast, and they all do a great job.
But, it's really Tim declaring to the world that he is too lazy to read...again.
Much like he was with Batman and absolutely every other adaptation that he's made. I had a girlfriend when I was an undergrad that absolutely totally loved a lot of books...but only ever actually read "The Mists of Avalon."...she was an art major too.
So, it turns into Tim Burton "artistically reinterpreting" something that he has never read and thus really doesn't know how to interpret in the first place.
