I want to like Goyer but I'm gun shy. Blade three was an excersise in lazy, uninspired film making. It was as if someone grabbed a book on the most cliched moments in cinematic history and he did them - all of them. The film showed no personality or visual sense whatsoever. And mind you, I actually enjoyed Blade 1 and 2.
BUT, he did pen Dark City which I have always like, he also supposedly penned a GR script that made the current movie seem like a ride at Disney, and of course he helped craft my all time favourite comic book movie, Batman Begins. So there's hope, just not much of it.
