I enjoy watching the prequels as eye-candy, but they aren't really movies. They're more like sappy video games. Perhaps they could have been made into movies with:

different story
different script
different director
different cast
different effects

I almost added "more CPY", but that goes without saying. The music I might actually keep.

Seriously, the one thing about the PT that made me really sad, was the Yoda lightsaber fight. That pretty much destroyed his character. After ESB, I pictured Yoda fighting with the force as his ally, with great efficiency and grace. A slight move or gesture here and there, bending the force to tie the opponent in knots. What a missed opportunity. Instead they stick his tail in a light socket and have him leaping around like a maniac, totally out of character and with virtually no hint of the force. It was painful to watch.
