being a long time SW fan from the beginning I think theres stuff that should have been done differently for the prequels though. I dont think the whole jar jar thing was great though it was'okay' and technically it was a bloody superb integration into the movie and done before Gollum pushed it to another level, nonetheless it was still an enjoyable movie.
The only thing I dissliked about the prequels was the cereal acting. While technically they were superb, I still think the Classic trilogy had way better craftsmanship. They really had to work hard to make the effects look good and believeable, and they were character driven to boot which is a plus in my book. I don't know how cereal acting could ever appeal to anybody.
