TMBTM-In my Ep2, Palpatine does appear to be the right man to lead the republic (I'm not sure if his true agenda should be revealed in which movie, but leading toward Ep3) and Anakin doesn't exactly "choose" the dark side, but he does reject the Jedi and leaves the order (the twist is its an amiable separation).
Very good IMO. :)
What I'm saying is that I'd like to see, at some point, Anakin doing evil things, knowing it's evil, but doing it no matter what because the events leads him to think that it's the write thing to do. And the audience shares his feelings (like in a vengeance movie ala Kill Bill, I don't know). I'd almost want the audience to scream with joy when the Jedi are killed; then suddenly feel ashamed for that. And I think the killing of the Jedi kids could be useful here.
Like: "yeah, kill all those fucking Jedi Anakin!"....."Oh shit, he also kill the kids? I did not want it to go that far..." I'd want the audience to experience the "angry, attractive and fun" side of the dark side, immediatly followed by its bitter taste.
and from that moment the story reveals the ugly side of the Empire. Anakin is too blind to see it though.
EDIT: sorry, it's getting harder and harder to follow the discussion and to make myself clear with my english. I'll try to make even shorter posts.
