My biggest problem with Episode 3 was how Lucas carried out the Jedi Purge. Darth Vader was supposed to be at the forefront of hunting down the Jedi, but Lucas' explanation that it actually was Vader, since he had just been named Darth Vader by the Emporer, was preposterous. Everybody that paid a ticket for that movie wanted to see Darth Vader in the suit whipping some arse. His follow up explanation: Vader was too recent from his injuries to be in any action. All that time waiting to see Darth Vader in the suit on the screen again only for a minute at the most...I felt like driving to Skywalker Ranch and putting my foot up George Lucas' arse.
