I became an OT "Purist" after seeing AOTC. I can't really remember when, but it was before I saw ROTS. I didn't have any fan theories about how Anakin became Darth Vader, but after seeing that movie, I realized that the story of AOTC couldn't possibly be it. The CGI probably didn't help, as it was less part of the definitive story of Star Wars, and more the ad hoc imaginings of George Lucas.

After ROTS came out, I felt that Star Wars was finally finished. Dead and buried. Then I saw the Plinket reviews, and considered that as a whole, the prequel trilogy was not worthy of being considered canon, especially as there were many continuity problems regardless of the style of the prequels. Consequently I have embarked on a quest to discover a good prequel story, and in the process I try to discover what precisely made the original trilogy, and indeed any good story, good.
