I don't know IDP, I still like a New Hope. Of course I was 8, and in Denver you could only see it in the Cooper, after waiting in a line around the theater for hours. The Cooper held 1200 and that crowd and experience made the whole thing the best film experience of my life- and that may be coloring it a bit now. There is no better moment in film than when Luke turns off his computer. (Okay, that is a lie, the balcony scene in To Kill a Mockingbird is better) That and the whole death star attempt is ust wonderful - of course I have the non-special edition laser disk version that isn't all F'd up by Lucas.
Empire disappointed me as a Kid, and return of the Jedi and the Ewoks was painful. Joseph Campbell had more to do with the success for the first film than Lucas, because he understood myth and storytelling.
I did fin myself chuckling at a few of the jokes in the Detours clip. Of course the Robot Chicken stuff has me laughing out loud.
