The actors and the chemistry was just so much better in the OT that Lucas didn't have to do much, he just sat back and let them work. The PT had terrible actors who probably needed LOTS of direction, namely Portman & Christensen, and their was a lack of chemistry. Now the best actors in the PT was, of course, Ewan McGregor & Ian McDiarmid. Jimmy Smits also, but he was so crippled with his lack of screen time.
