Personally, I always thought Anakin's character arc should've been exactly opposite. He should've started as a mature, noble, selfless, likeable character, and transform into an evil villain. Instead, we got an annoying, unrealistic little boy who transforms into a leary, creepy, whiny, overbearing, unbelievable jerk, and finally turns into the cool-as-ice villain from there.

Unfortunately, if I even think about the prequels while watching the OT, I think of Vader as a whiney little bitch instead of the true evil villain he is. That's probably why I don't think of the prequels much :)
