(awwww, he's so cute) and their reaction at learning that he was in fact YODA...the man, not just a cute little creature. Because, back then, when SW was good, important story elements like that were surprises...as they were meant to be.
The, "I am your Father" moment was a dramatic and shocking moment in the theater..a real socker of a moment. But, as we all walked out of the theater, I don't think we all believed it. As an eight year old I was ecstatic with the whole movie, but I remember explaining it to my parents, who were waiting outside the theater to pick us up, that Vader was probably lying to Luke to get him to turn to the dark side. I was totally unsure of it all until Jedi came out. It was a topic of much heated debate at school I can tell you. Ahhh, memories!
