Yes, Empire Strikes Back is the greatest sequel or part II in movie history. At least that’s what the boys from “Scream 2” said.
That’s because “Empire” had the expert director Irvin Kershner at the helm.
The real problem with Star Wars is that it is written for two very different audiences because of how it makes money. Most of the money actually comes from licensing toys rather than ticket sales. So given that, you have to market to the age where kids will buy the toys. This is why they keep introducing new spaceships, robots, and creatures with every movie too. It makes you keep buying toys to keep current.
Then you have the movie goers. In 1977, they were the same age as the toy buyers, but now they are the nostalgic toy buyer's parents. They watch the new movies for nostalgia, but are always disappointed now because their more adult tastes are competing with their childhood memories.
