The one problem I have is in the acting abilities of Natalie Portman and Hayden Christensen. Talk about telephoning in your performances, I've seen cardboard cut-outs with more expression. They don't have anything like the charm of Han Solo and Princess Leia. Even Mark Hamill as Luke Skywalker was infinitely more interesting than Christensen's portrayal of his father as a young man.
Oh, well, I'll go see it and hope they've improved.:)
That is by far my biggest complaint of the prequels.
