I think I understand how you feel. I've had my ups and downs with Star Wars. The prequels are a dim comparision to the original trilogy. I could go on, but I'm sure it's nothing new to anyone here.
However, I think you may be letting your cynicism get the better of you. I don't think this is the end of Star Wars (especially the Original Trilogy). In other threads, I've seen you post things to the effect that there is nothing new to discover in Star Wars, such as your out-of hand dismissal of "Luke's missed Death Star chasm throw" as well as your dismissal of the remote possibility that an advance copy of ESB was screened in some theatres.
This may sound naive, but I am amazed by the new things I'm continually finding out about the Original Trilogy. Like a month ago Trooperman dug up some old music by Korngold (sp?) that was an obvious inspiration for the Star Wars theme by John Williams. And I haven't seen Jambe's Returning to Jedi yet, but I'm sure there's some stuff in there I've never heard or seen before (FYI, I am 34 years old, and have been a Star Wars fan since I was 5).
I hope you don't give up.
