I just watched this and I think it was great. There was the problem with the hand of course, as it is never explained how Anakin has a metal hand, but other then that I didn’t catch any serious loop holes. I’m not a big Star wars fan, so I wouldn’t notice all the subtle errors anyways.
Most of the cuts were nicely done, except maybe three of them that weren’t that great. I watched the one layer version and the picture quality wasn’t that great, every time there were large areas of black, the picture was pixalated.
All in all, it was the best effort I have seen so far of re-editing the prequels.
