The battles in the PT are only due to advanced computer technology we have today. Had Lucas access to today's technology in the 1980's the prequels would be crap compared to the OT.
And how do looks matter in the movies? Just because someone looks better doesn't mean the movie's better. For me, Sir Alec Guiness just commands much more respect and power than Ewan McGregor.
And EP 1 & 2 had horrible storylines. Trade federations, Jar Jar Binks farting, midichlorians all pale in comparison when you see the Imperial Fleet about to jump to hyperspace with Imperial March playing the background in ESB. Episode 3 might be better, I don't know.
And Luke is more powerful than Anakin.
