I enjoyed the second and third episodes, think they fit very well with the original trilogies. However, the first movie I find really bad, especially since Anakin is like 7 years old and finds emotional affection in Padme, and she finds it in him.
Sure enough, had their love actually started to develop in the second film I'd see it less of a problem.
Also in TPM the entire pod racing scene is unecessary, a filler scene, if you will. That said, I think the third episode fits well with 4 through 6, and second being a decent movie all in all. First one is kind of a disgrace.
