I don't have as many problems with remembering the prequels while watching the originals as I thought I would, because I've only seen ROTS once (in the theatre). I own the DVD, and I've tried to watch it 4 different times, and every time I've fallen asleep about 20 minutes in.

I'm starting to get more and more "Star Wars '77 Only" as time goes by. I still really enjoy ESB, and certain parts of ROTJ (pretty much all of the Luke/Vader/Emperor scenes, especially the final lightsaber duel....also Leia's scenes in Jabba's Palace, only for completely different reasons.). Since I saw ROTJ first, it was hard for me to watch the original without the sequels in mind, but I'm slowly getting to the point where it's the only one that I really care to watch repeatedly (it's also the only Star Wars movie on my iPod at the moment). The Radio Drama is great though!
