My ideal prequel trilogy would have depicted Anakin as a quiet, emotionally repressed drifter pilot with no knowledge of his past, his anger stemming from his sense of rootlessness. When he befriends Obi-Wan, he initially declines to take up Obi-Wan on his offer to become a Jedi and fight in the Clone Wars, which deal primarily a dying race of Darth Maul-esque creatures using cloning technology to keep their race alive and are trying to destroy the Republic for their oppression. Obi-Wan eventually persuades him, and as Anakin confronts the Dark Side, his personality gradually splits in two - the essential good half that is Anakin and the dark, mean, sadistic half that is Darth Vader, until finally the fragmentation causes the Vader personality to overwhelm and devour the Anakin personality. When Obi-Wan confronts the pre-mechanical Vader, after a spectacular fight, he throws down his lightsaber in a fashion similar to how Luke rejects the Emperor in ROTJ. Vader almost kills him, but what little bit of Anakin is still in him won't let him, so he hurls himself over the side and into the lava, only to find that death alludes him and fate leaves him as the half-maimed machine man villain we knew and loved from the old trilogy.

Oh and his lover, the mother of Luke & Leia, would have been a lady Jedi just to cut down on time constraints and leave out all that crap we put up with in AOTC about forbidden affairs 'cause my Jedi would not have believed in that "no love" junk.
