Pepper was not good but the direction is most at fault especially the phenominal number of dutched angles which, I'd guess, were trying to engender a kind of comic book vitality to the proceedings but just ended up convincing the audience that no one had really thought anything through and the director was trying to distract with choppy camera angles. I've seen a few other films directed by Roger Christian which were much less 'stylish'. At best they were competant. He was totally out of his depth in Battlefield Earth.
I would like to seen what James Cameron, Alex Proyas or John McTiernan could have done with this film.
