I must admit it was a questionable choice on the part of George to have a different villain for each episode. At the very least, it’s a good thing that nobody kills Dooku until Episode 3.

That being said, I do appreciate the original idea that Qui-Gon’s death was what pushed Dooku to the dark side, rather than him being the one to do it. It makes his character far more sympathetic and understandable. Perhaps even a little grey and morally ambiguous. I feel like this concept would just force him into the two-dimensional villain role with no discernable character motivations. To that end, I think I actually prefer Maul being the one to do it.

EDIT: If anybody has the VFX skills, I’d actually much prefer Dooku to be present at Qui-Gon’s funeral, taking the place of the super obvious hint shot of Palpatine after “But which was destroyed, the master, or the apprentice?” I realize this would contradict Tales of the Jedi, but it’s honestly such a missed opportunity. Mace is too foolish to realize that no Sith was destroyed by what occurred, but rather a new apprentice was born.
