What about this:
Dooku is not Sidious's Padawan learner. He already was a Jedi Master who left the order because, as he says, of all the corruption in the Republic. In the end when he talks to Sidious it seems like he has been a part of the plot for a longer time than just since Maul's death. You must think of who ordered the Clone army and such. I think Dooku is a classic example of why there shouldn't be more than two Siths. He thinks he is playing with Darth Sidious, he has his own agenda and wants to eventually kill Sidious and take his place. (A common ocorrence in Star Wars) He is, obviously, much mistaken. That's why he will be the bait for Anakin to complete his journey to the dark side. Sidious his playing him! Making him feel like a peer, like his right arm or something.
But in the end I believe that what Sidious wants is not a competent side-arm, what he really enjoys is turning a good person into a bad one. He is constantli doing that, with Dooku, Anakin and Luke... Darth Maul was probably a nice guy🙂
In a generally good, healthy, take no offence, just an expression kind of way...
Anyway, geeks rule, look at GL and Bill Gates, ultimate masters of geekness (that's a cool word I just made up).
Remeber when GL said he wanted te rights to the franchise of SW? The guys at the studio must have said: What a geek!
