I prefer "hack" :D
He's, like, putting completely wrong ideas into his new films, adding changes to the originals with completely absurd rationalizations, keeps talking about "movie for kids", about his "vision" and how the original versions should best cease to exist, despite two of them not being technically his, how he just makes Dooku roast Anakin for no other reason other than having Obi-Wan fight him alone for a while, then includes a space prophecy for no reason that he doesn't establish in the movie, but explains in a completely laughable DVD feature, then suggests to watch the prequels first while they're clearly written as PREQUELS building on top of what is coming after... he doesn't know what he's doing, he just does and says random things without any justification or thought - he's a hack :D
