Maybe if it were a one-time stance for coolness sake, but they do it at least three times I think. Really, think about how dangerous standing like that would be, and how unlikely it is that they would both adopt this sort of stance after years of training. It's more like two fighters knowing they look cool on camera and not really fighting.
To that duel's credit, I personally like the lighting during that scene where the blades light their faces and we can't see the actual moves so much. I find that worthwhile and OT reminiscent. Still, I just imagine if Dooku were fighting more along the lines of a proper fencer...that would be sweet in my mind.
I'm not asking for a total overhaul, but like you said, an OT touch up. I know certain things could never even be changed, but I'm just giving reasons why it's inconsistent with the OT and therefore bugs me a bit.
Pacing is another thing that feels too different from the OT to me. TPM in particular felt rushed much of the time with not enough dialogue to fill a decent scene, and yet the dialogue present telling us so little (Your Highness, we're going to Tatooine." "I don't agree." "Trust my judgment." End scene). I wish we got more character and that scenes didn't feel rushed. I don't know how this could be achieved, as editing usually involves more cutting than adding, but this thread is sort of like the radical redux threads.
