I was lucky enough (read: old enough!) to see the Special Editions of the Original Trilogy when they were rereleased in theaters in 1997. The changes Lucas made are still mostly nonsense, but I'll always be glad I had the chance to see those movies on the big screen.
Then came the Prequels, and whatever anyone wants to say about the quality of those movies (... they're not very good!), it was really fun to be in the cycle of a new STAR WARS trilogy while still, basically, a "kid" (they came out when I was 12 through 18). The hype, the speculation, the promotion, the merchandising. Even though I don't think the movies are good, I have very fond memories of everything surrounding them.
