I watched the first Star Wars movie 27 times in the theater. That number is so high because I often went in for the matinee and watched every showing the rest of the day.
I was like George McFly in the early 60’s and would rush home from school on Tuesdays and Thursdays to watch “science fiction theater”. I even saw the first Star Trek “sneak Preview”, “The Man Trap”.
I was sort of obsessed with Science fiction back then.
But anyway, just to say you are right. The only Sequel I really liked was “The Empire Strikes Back”. I used to call it “Star Wars for adults”.
And not to put too fine a point on it, Star Wars was not science fiction. It was really Space Fantasy.
But yeah, I liked the first Rambo. Then it got lame, except for a single line in a sequel: “Do we get to win this time?”
Again, I liked the first Rambo since I'm from a military family and support veterans whenever I can. He got a raw deal in the movie from the sheriff.
