A midget? Wood is far from a midget. He also managed to be pretty damn sneaky and cunning in Sin City. For all the talk about how killers shouldn't be hulking maniacs (no pun intended), I think it's pretty funny that people are taking such issue with his height.
And as far as the original being a film that gets by on its bad charm, I don't see it that way. I've enjoyed sleazy films in the past, but those films always had something to keep me watching. I didn't have that with Maniac. The plot is also so simple that it could easily be improved upon. There's a framework there for a good story, and perhaps this film will make it work. There's no guarantee of that, of course, but I'm hopeful.
