ROTJ was a bunch of movies packed into one. Aside from the Death Star (Which might have been better served not appearing in Star Wars at all until now), it really feels like it tries to close too many threads at once. If Lucas could’ve gotten away with more movies in his franchise, we might have had a more natural progression to the events of ROTJ.
Except for the Ewoks. Wookiees would work significantly better. I blame the Holiday Special.
