Episode III was a major disappointment. The number of inconsistencies within that universe skyrockets again, as this movie is a series of artificially and forcefully strung together events. That wouldn't be so bad if the dialogues weren't even more artificial than the plot. Some say bad acting, I say you can't deliver these terrible lines with any credibility, no matter what your acting skills. Want to show your position to the vocal but very wrong majority?

And check out these people, who are just so damn right about this. Here, and here.
Update : 2028 hours, another good review from the Montreal Mirror.
