I just can't resist bashing Christensen's performance. Truly awful. WTF was Lucas thinking?
Lucas was very good at getting inferior performances from good actors. So this thread is a little unfair because we're dealing with a director who is just not good at directing. He's a 2nd unit style director who knows how to choreograph action scenes but is in over his head trying to convey real drama.
In this respect he's kind of the opposite of someone like Quentin Tarantino who is known for being able to get awesome performances from actors who had destroyed their reputations with B-movie dreck (like David Carradine who was riveting for every frame he was in Kill Bill).
