Grievous vs. Obi-Wan.
In the books we were led to think that Grievous was this monster war machine. The most feared general by jedi! Then Obi-Wan comes to Utapau, gets in a duel, and cuts off 2 of his hands, like they were nothing! Then the worst part is he died by a blaster. I mean, come on! A blaster? Laaaaaaaaaaaaame!
