If there hadn't been a tale of the fight taking place on a lava planet then we would have no Mustafar. Obi-Wan and Anakin are shown fighting-completely impervious to the lava. Just from their close proximity they would be in pain just from the intense heat! the intercutting with the Palpatine/Yoda fight is annoying and lessens both encounters. The Yoda battle suffers as it is cut short and the epic battle of the masters is left pointless.

On this subject, Palpatine should never have fought. He constantly makes little funny faces and looks pathetic. If he didn't fight in ROTJ why does he all of a sudden have to flip around like Yoda?

I wish the battle had not been intercut, and been more confrontational. As it stands we see two guys in a massive overkill of CGI doing the same fighting repeatedly. It is not epic: it is monotonous! We waited to see this for years, and all we get is this one thing? Anakin becoming extra crispy fried?

Hopefully George will come to his senses and repent for his sins by making a film entitled:

Obi-Wan's Damn Fool Idealistic Crusade
