It's true that anime does not make for good live action.
I think the only reason anime movies are so bad is because they want to make money, not pay tribute to the anime in an artistic way.
Bleach would be VERY hard to make into a movie. There's too much content in the anime... To many characters... It would be really hard to do.
I have been into film studies since I was a kid... I love creating short films and scripts. I have a great eye for detail and story telling. I can see making a Bleach film in my head, but actually getting it off the ground would be too hard. Having to go through production companies that would say no to a lot of things, and "Hey stick this character in that has nothing to do with it!" or "Let's change this character's age to appeal with a different fan base!" etc.
Bebop will be horrible, I say. But that's just the fan girl in me talking :P
