I was only 9 when I saw ESB in 1980, but remember it so clearly.
My Dad told me to close my eyes as we were coming around the corner of the street near the Cinema. he led me to the queue (line) outside the Movie theater and told me to open them. I was staring right at the poster, I was so happy as I had been going on about how much I needed to see this movie. When went inside they had Star Wars figures and Vehicles behind glass cases. And when I was watching it, the shock that Vader was Luke's father is something I also still remember. My Dad took me again to see a double bill with Star Wars and we stayed and watched both movies.
I can truly say that not only is this film my favourite sequel of all time, but the best movie ever made
