I think the idea of a deserter Jedi other than Anakin could have been interesting, but they didn't play with the duality nearly as much as they could have.

The guy does have the distinction ONE Sith who doesn't go absolute batsh*t when he duels. At least, in comparison to his cohorts.

You know, the prequel trilogy had too many characters. Especially antagonists. Had Dooku been the only one, apart from Sidious, this might be a different conversation.

Tru dat. He would've been more interesting if they'd actually gone with the moral ambiguity they hinted at in AOTC, and had been sincere in his plea to Obi-Wan in prison. They basically threw ambiguity out the window once he started talking smack at the Jedi in the arena.

He'd have sort of an arc throughout the trilogy:

Ep. 1 - Dooku (instead of Sidious) appears as the mastermind behind the villains' army. Years ago he couldn't substantiate his claims about the presence of the dark side in the Republic, and the Jedi fear he is mentally unsound and may have fallen to the dark side himself.

Ep. 2 - Dooku's forces appear to be preparing for war. When confronted by the Jedi, he insists that he will save the Republic and the Jedi from the evil they can't see. Now convinced of his madness, the Jedi attempt to subdue him, and he reluctantly fights them as he attempts to make his escape.

Ep. 3 - Dooku (instead of Grievous) is on the run, growing more desperate as his forces clash with the Republic. At last Ben has him cornered - only for his own troops to barge in and attempt to kill them both. It seems Palpatine has convinced the public that Dooku never really left the Jedi Order, but was secretly building his army for the Order so they could make a power play. Both realizing they'd been played, Ben and Dooku together try to rally any remaining Jedi for a final stand. Dooku finally falls in the ensuing battle against Vader and his troops.
