I prefer the original colour of the lightning to the PT one, and I like how much "bigger" it is, rather than thin little arcs, they were think, and damned nasty looking. Obviously it looks outdated, and does need to be redone, but I'd like it do be as close to the original as possible.
Of course, thanks to the PT you get the same problem with Luke's green lightsaber, the surprise is gone. Obviously, it's hard to avoid (unlike the green saber) in the PT, since why the hell wouldn't Palpatine use his most deadly attack in ROTS, but still, the exact moment when Palatine lets loose a load of lightning out of his frigging hands, is one of the best surprises of the OT, for me.
Also, which one is Jerjerrod? Sorry to ask this but I've honestly never heard of him before this topic. I'm not that familiar with EU, and in all my many viewings of ROTJ, I've never noticed him. I assume he was supposed to be more important in earlier drafts, or something?
