Even though I saw all 3 OT movies in the theater, Jedi was the first one I was old enough to really enjoy the hype. I was going into 5th grade when Jedi came out, so I was a full blown SW fan at that point, and couldn't get enough of it.
My first memory was in the summer of 1982, and I was over a friends house eating lunch and her mom said, "I just read that the 3rd SW movie is going to be called Revenge of the Jedi!" I was so stoked, as the first thing I though was Luke was going to kick some ass and this was his revenge against Vader.
I remember leading up to Jedi that because there was no internet that you could actually goto the movie and not worry about spoliers. I told my one friend (who saw it before me) not to tell me if Vader was Luke's father. The only he said was that Luke is a badass in Jedi and chokes the guards at Jabba's palace to get in.
After I saw iit with my 2 older brothers, I was on a high for days. I was young enough not to be bothered by the Ewoks like I am now, and I was fascinated with the talk between Luke and Obiwan on Dagobah and that there was a backstory behind all of these movies.
