The problem with Tim Burton is not that he repeatedly casts Johnny Depp and Helena Bonham Carter. That’s silly. Was it a problem that Akira Kurosawa repeatedly cast Toshiro Mifune? That Ingmar Bergman hired Liv Ullmann and Max von Sydow over and over? That Scorsese had an amazing 25 year run with Robert DeNiro? Of course not.
The problem with Tim Burton is that he has nothing left to say.
….An additional note. One useful thing in that linked piece is to suggest Burton might benefit from doing something entirely different. I do agree with that, though I’m extremely skeptical of his ability to pull it off. One thing I love about David Lynch’s The Straight Story is that not only is it a very fine film, but Lynch also clearly proved that he work in very different types of film with great skill. His weirdness is not a crutch, as opposed to Burton.
