Nah, the environments got swapped, but the character actions are basically the same. They meet a tiny wise sage strong in the force, where our hero descends into a hole and has a vision, before getting wrecked by the person she just had a vision about. (Empire), and then the run on the giant superweapon that makes the first Death Star look like shit, featuring Han Solo leading a small strike team to take out the shields so the attack run can begin, an attack run that ends with the ship flying INTO a superstructure, blowing it to hell, and flying back out again, while a climactic lightsaber battle takes place among three people (JEDI).
elements from all three movies are consistently sprinkled across every act of the film, but the key moments seem to follow that mixtape structure: Beginning = Star Wars, Middle = Empire, End = Jedi.
