Why is Hollywood so screwed up?

Neil Gaiman sets the record straight as to what's going on with "Constantine" as it pertains to Alan Moore. It's interesting to find out that Moore was really upset over Larry Cohen's ridiculous suit, which basically said that Moore created the comic book "League of Extraordinary Gentlemen" so Fox could rip Cohen off. But Moore's response to this is rather odd, but typical of him. Rather than coming back against Cohen, he just gives up all credit and money for movies based on his work.
As for "Constantine," a movie based on the comic book "Hellblazer," it's going to be royally screwed up. Well, there's a chance it might be good, but the weather still looks pretty hot in Hades to me. "Hellblazer" is a comic book about a Brit sorceror of sorts. Being British is not just a small detail, a little character background, it's essential to his character. He's also blond. So what does Hollywood do in its infinite wisdom? Cast Keanu Reeves. If that's the starting point of this movie, where can it go from there? Unless it gets screamingly good reviews, I'm going to stay far away from the movie.
