At least he looked cool though. And in the prequels, less dialogue tends to be for the better. He still beats Count Dooku and General Grievous, who had characters, just really bad ones. That’s worse than a guy with no character but a cool lightsaber and badass style.
Maul is mysterious in episode 1 and a badass. Clone Wars expanded him a bit more. But in the Rebels finale I felt he received a lot more interesting characterization.
