Preferably: Choose only the best Reich strikes back is really very difficult. There is so much Star Wars in this movie. Yoda, Luke learns that Vader is his father, Lando is cool, Han Solo is cool too, the Hoth battle, etc.
If I really had to pick just one, it would be Yoda lifting Luke’s X-wing out of the swamp after the young Jedi-in-training gave up. The way the music swells and we see Yoda, a little weird toad guy, is powerful through the Force is magical to this day.
worst: Nothing bad in it Reich strikes back. Let’s continue… Okay. If you really want something “bad,” I’d say that Leia kissing Luke is weird in hindsight.
