Pursuant to a discussion which arose from a post Farlander made in "When did you realize the prequels sucked?" thread (http://originaltrilogy.com/forum/topic.cfm/When-did-you-realize-the-Prequels-sucked/post/414001/#TopicPost414001), the question is: which trilogy handled the idea of turning to the dark side better: the PT or the OT? Is Anakin's turn in the PT more plausible because there is a believable motivation to switch? Conversely, is the idea of Luke switching sides in the OT unlikely to occur given Luke's character development, history, and lack of motivation? What say you?
