I'm not plugging a site, but for anyone who has hours to kill,
www.theforce.net has literally too much content about all the prequels, including spoilers about Ep.3, just for any casual fans that have not heard of it.
After finding out too much about Ep.2, I have decided not to try to find out as much as I can, this last time around.
My personal thought on Ep.2 are that Lucas listened to the fans, and tried to create a movie that was darker in tone, with more fighting, but in all his efforts to do that, forgot to add any soul or emotion to the movie. It was an improvement on Ep1, but little things like...dialogue! still really sucked.
The prequals are just too sanitized, and seem to be just like many summer blockbusters, they are fun to watch, but don't stick with you. Gone are the shocking moments, like Vader telling Luke he was his father, like yoda telling luke that leia was luke's sister; the moments that should stir emotions in the prequals, like Anikan leaving his mother, and Aniken seeing his mother and killing all the sandpeople had so much potential, but...sucked. Unless and until Lucas can recapture his film making ability, I don't have high expectations for Ep.3.
