I’m more bothered by how he kneecapped every other Prequel villain. Darth Maul could’ve been the next Darth Vader but he gets killed in the first movie. Asajj Ventress could’ve been a decent replacement but she herself got replaced by regular old Christopher Lee in a cape, who himself gets killed off immediately at the start of the next movie. General Grievous is actually great but showing up only in the last movie it’s too little too late. Compare all that to how Darth Vader and Kylo Ren get entire trilogies to develop and the difference is night and day.
