Anakin turning evil should have been because of the Clone Wars and getting 'caught' up with all the politics of the galaxy. Anakin should have never choked his wife, nor killed loads of kids 10 seconds after he says, 'what have I done?" It just makes him a sociopath, and those guys are never redeemed. Think of Jeffrey Dahmer and all the other serial killers, they are never redeemed at the end of their life, cause they are so reviled by the public for their awful crimes, and that is the way I feel about Anakin now. I look ROTS and think, The guy is a baby killer and wife abuser, and he gets to smile back at Luke at the end of ROTJ while Luke is not told of ANY of his crimes? What kind of message does that send?
Anakin should have been killing jedi like the Conehead guy, and all the other jedi on the council that we atleast got to see during the PT movies. He should have turned cause he either felt the republic was the bad guys and the jedi were the evil doers, and that should have come from Palpatine continuously praying on his naivity for 3 movies. The whole dream and Padme is just plain stupid and to me and easy out for Lucas not coming up with something very interesting.
Wars bring out the best and worst out of people, and there are many grey areas when looking at a war. Is the Iraq war worth it? Was the war in Vietnam worth it? Should the Americans dropped 2 Atom bombs on Japan in 1945? Lucas could have challenged the viewer to actually consider Anakins stance in the Clone Wars, and maybe think it was wrong, but understanding he may be right.
There would have been nothing more cool then Anakin/Mace going at it in ROTS as part of the Clone Wars as Mace & Co. go after Palpatine, and Anakin finallly takes Palps side by killing Mace and then truly going over to the darkside. Then he begins to track down all jedi through ROTS as he battles them one on one which eventually leads him to Mustafar where he & Kenobi meet in their climatic duel. As Padme hears of Anakins turn to the darkside, she gives Luke to Kenobi to take to Owen, and takes Leia in hiding on Alderran with her friend Bail Organa. That would have matched up perfectly with the OT as now we understand why Vader stood by The Emperors side in ROTJ.
Instead we get a guy who has a bad dream, and then turns in 3 seconds, and kills kids and chokes his wife, and ends up smiling as a young guy as a force ghost in ROTJ as Kenobi is this old crusty man standing there next to him. Sorry George, I just don't buy it.
