Thanks.
Darth Maul... he has a colorful history. He survived after TPM, and was found by Savage Opress (his black and
green brother) in some junkyard with spider legs made of junk. He was taken to Mother Talzin, the leader of the Nightsisters, who used her magic (the Force by a different name, really) to give him fancier normal robo-legs. Then he and Opress palled around and did stuff, killed some dudes, fought Obi-Wan a couple times, lost some limbs, teamed up with some Mandalorian traditionalists, killed some more dudes, and took control of Mandalore. Then Sidious decided that Maul was a threat, schlepped his arse over to Mandalore, killed Opress and cowed Maul. Then TCW ended, so buggered if I know what happened next (might be covered in the future).
It sounds a bit silly, really, and I imagine a lot of people hated it (including our own Andhaira), but it was fun enough to watch (especially that last duel, with Sidious laughing like a maniac throughout), even if some of it was incredibly stupid.
Also, there's some other EU stuff with Maul coming back on I think one or two more occasions, though I think one was as a ghost and he fought Darth Vader or something. I don't remember the details offhand.
Compared to comic books, Star Wars is positively tame. Most characters do stay dead, Force Ghosts notwithstanding. I mean, Palpy came back in a series of clone bodies, but that's explained as a some Force technique he came up with (and a testament to his power), IIRC. It's mostly okay, though. You know, until the bring back Darth Vader for the sequels or something. You know they very well might.
EDIT: And yea, Old Palpy is strong yeah, but I just couldn't take his killing 3 Jedi Masters in Ep3 seriously. I don't deny that this is within his abilities, but the way they did it in the movie felt so...I dunno, hamfisted?
That scene was awful, definitely. In-universe, he's just freakishly powerful and his mastery of Force Speed allowed him to kill them before they could do anything. And, in-universe, those three Jedi were all pretty well decorated, so not complete mooks (hell, I can name them). In the movie, it just made everyone look incompetent, the Jedi for standing there like idiots, and Palpatine for telegraphing his attacks so obviously. The duel with Mace Windu was pretty anemic too, really. (Though I don't deny that Ian McDiarmid was fun to watch in it. He seemed to be having a ball.) The novel did a better job of it, but canon and all that.
