Star Wars is a Parasite
There are three Star Wars movies. They came out in the 70s and 80s. We got two great movies and one good-but-flawed movie. All in all a classic trilogy for the ages. It was a great run but it ended a long time ago.
All "Star Wars" branded product since then has just capitalized on people's nostalgia and love for the original movies. Basically all the new movies know how to do is evoke Star Wars nostalgia by re-creating scenes and situations from the original movies, but with no substance behind them at all. If the original trilogy never existed and these new movies were somehow made, they would fail, because they're not good movies. If you look at the actual plots they're barely even coherent movies.
The ONLY reason these movies are hits is because of people's love for the original movies and the desire to recapture that feeling. The new movies are literally parasites on the goodwill created by the original trilogy.
