A bit late, but I also don't understand why Orci's directing the new Trek film.
I have no idea if he'll be a good director or not. But, giving him such an important film for his first project is a bad idea. On one hand, it's almost impossible for him to fail. But if he does, it will be a disaster.
Because the film's so big, it's not like he's going to have a lot of power or opportunities to learn. You know that the cinematographer, editor, art director, composer, etc. will be expected to pull a lot of weight to make sure Orci's inexperience doesn't damage the film. A first time director needs to be able to make decisions about how a scene is shot, look at the dailies, realize he fucked up, and use that experience to do better in the future. Star Trek can't fail, so Orci won't be allowed to fail, which means he won't be able to learn, which means he won't be able to become a better director.
Maybe Orci's a directing savant, but you can't make that assumption. Huge mistake by everyone.
