I don't know if you've already gone too far for this, or if you've already decided to do this, but something always bothered me about episodes 2 and 3--the fact that lightsabers just slice through things like they were butter. Of course that's what a real lightsaber probably does, but in episode 1 (my favorite one of the PT now after going through them all objectively) when a lightsaber hits something, it's not so much of a slice as much as it is a smack! And it's very satisfying--check out the first few scenes when they're slicing up the battle droids to see what I mean. It makes it seem like it's harder to use a lightsaber rather than in the other two prequels where you can swing the thing around willy nilly and do just fine.

Anyway, just a thing I was gonna do if I ever reedited the films

Oh! btw--sweet Palpatine sequence, the idea that he was fried with his own lightening doesn't seem as gay a premise the way that's edited!
