I know this is all subjective, and the title is things YOU think.....", but I love the early Star Wars trilogy ( episodes 3 -5).
I was heavily into sci-fi when the first film came out in 1977, and actually got invited to a prerelease screening in a cinema on Tottenham Court Road.
The audience ( admittedly all scifi fans,) actually applauded the titles.
What struck me at the time was that, unlike so many previous sci-fi films, things in this film looked used - like Luke's battered speeder.
The films started going downhill when they got Jim Henson and Frank Oz involved - Jabba's lair is a glorified Muppet Show.
