Long before that; the Star Wars "Holiday Special" was in 1978.
The movie franchise become a clown show with the Ewoks in the third one as well as the soap opera of Darth Vader being Luke's father and Princess Leia being his sister.
Viewers can't accept that it was one and done.
The only good thing that came out of it after the first one was “Space Balls”.
Yeah, everything that came after is "Spaceballs 2: The Search For More Money".
