The ret-con/fan-wank answer is because it’s Young Anakin who shows up with a cool ghost body at the end of Jedi, so Old Anakin wouldn’t fade away.
The actual answer is … good point. 
Because he hadn’t chatted the procedure with Yoda or Qwaigon? And if Anakin had turned good at the last minute and still retained a body to be cremated, doesn’t that imply that Yoda’s death was methodical and intentional, like Obiwan’s? Perhaps in order to disappear a Jedi has to do it like a trick, giving themselves unto death rather than being killed?
Is there any evidence that Mace Windu intended to kill Palpatine? He’s still using his sabre at that point because Palpy is still shooting out the Force lightning, and Mace (the greatest lightsabre master among the Jedi) is using his weapon to deflect the lightning. Turn it off, and the lightning that was frying Palpatine would be frying Mace instead. It seemed pretty clear to me, though, that the objective was to bring Palpatine back alive, to stand trial, if at all possible.
Yeah. Oh, yeah.
Luke defeated Vader is single combat because he gave in to his fear and anger. Far better he stayed calm and focused but hey, whatever works.
Mace Windu plain and simply fucked up. When he had Palpatine down and Anakin is pleading with him to stop Mace gave into the dark side himself (anger and frutration) and determined to apply ‘justice’ (in an old testament sense) himself and not go through channels. That was, IMHO, the last straw that forced Anakin over to the dark side. Man, the Jedi were all over the place.
That’s the dark side’s “black and white” version of it. The Jedi live in the grey area where judgement must prevail over dogma. Mace was going to dice palpy because he knew Palpy had control over the senate and the courts (like Bush) and that justice could not be obtained through normal channels. Anakin (already a Sith at heart) couldn’t see past the black/white condition of not using what he considered to be excessive force against Palpy and…intervened. It’s a fine distinction between Mace wanting to kill Palpy the dictator and Palpy having Anakin kill Dooku the competetor, but I think it had to be made.
Could it be because there was little left of Anakin’s body and there was too much connection with the mechanisms that were Vader’s? I.e. Vader’s body had to be destroyed in order to allow Anakin to become one with the force (or something).
The lightning thing does happen, but then Palaptine stops it (whether he’s actually weak or just pretending is uncertain). Mace prepares to kill him, and even says that he has to be killed since he has control of the Senate (if they leave him alive, there’s a good chance he’ll get out of it). Mace attacks, Anakin stops him, Palpy blasts Mace out the window.
Mace definetly wanted Palpy dead.
I think it is certain he’s faking. He only has a moment of rest before shooting lightning again and killing Mace Windu. And he even comments on it, saying, “Unlimited Power! Unlimited Power!”
He’s basically saying, “You fool! My power is unlimited!”
I had a large, spirited “discussion” with many people on this topic when Episode III first came out–the results were about twenty people who agree Palpatine was faking weakness versus one who thinks he was legitimately tired.
There is so much wrong with that article that I wonder if it is purposely written to make the author sound like an idiot, a la The Onion.
The entire premise of the piece is that Luke chose not to kill the Emperor when given the chance. But - as anyone who has actually seen the movie knows - Luke did take a big swing at the Emperor with his light saber, which was handily blocked by Darth Vader (thus beginning their duel).
Sheesh.
If a chill runs down my spine just reading the synopsis of that scene, should I get professional help?
For the record, the main character in Episodes 4-6 is Darth Vader.
Episodes 1-3 are consistent, in that the main character is Anakin. That’s the only thing I liked about those movies…
I can say for a fact that Qui-Gon does not appear in any of the movies after The Phantom Menace (except for a couple of recycled voice cameos). I don’t know if this applies to Inigo, but I think the perception that he does is a likely side-effect of watching the series in Episode-order (I-VI) as opposed to release order. If you see the series as “The Rise, Fall and Redemption of Anakin Skywalker,” then it would make a lot of sense for Qui-Gon to show up at the end. Not for Luke’s benefit, but to provide some touching closure for Anakin’s character. As it is in the “new” editions, we see young Anakin (who Luke never knew) with old Obi-Wan (who Anakin never knew) and Yoda (who Anakin never got along with). This is just one of the ways the general suckiness of the prequels actually reduces the quality of the OT from a story and character perspective. 
I believe the author had his tongue firmly planted in his cheek.
Well tired or not, he was definately scarred, and permanently so by the reflected lightning attack.
