I saw AOTC in IMAX and the only part that I liked was the battle between Anakin (blue saber) and Dooku (red saber). Why? Because me and my best friend looked at each other and said "What does this remind you of?" It was the closest we were going to come to seeing something like Luke battle against Darth Vader on Cloud City. You could feel the hum of the saber flow under your seat as each twirled from frame to frame.
Dammit. For the 2007 release, Lucas should forget about that crappy "1950's drive-in 3D" movie, and just put the trilogy in IMAX. Of course it would be the 2004 CGI-fest, but I would be temped to see them in IMAX anyway.
