Dooku was one of the best character concepts for the PT and also one of the most criminally underused. I would have loved to see him develop some kind of tragic hero role (because, if you think about it, Dooku was right and should have been played as more grey than absolute evil). Or perhaps developing a relationship with Anakin to draw him away from the Jedi as his apprentice, which Palpatine turns against him in some way. I dunno. There are a thousand better ways to have done it.
Yes all this. And the better ways should have started by NOT calling him...
Darth Tyrannosaurus. "Darth" anything was already a losing proposition, but then the lumbering-and-extinct-monster-with-a-peanut-sized-brain-evoking "Tyrannosaurus" just renders the character entirely nil.
