I see what you are saying and agree as a stand alone story,
Rogue One is excellent. But I was referencing the overall series, if we want to see a healthy Star Wars continue. However, when a new good series story pops up with new characters, that not only do I like, but maintains the original Star Wars vibe, I’m good with a sequel if it can maintain the narrative. I’m ok with trilogies with connected stories if they are done well.
Referencing series with connected episodes,
Lord of the Rings and the original
Star Wars trilogy sit at the top.
X-Men 1 & 2 exploring Wolverines past was excellent.
Casino Royale and
Quantum of Solace were excellent.
The Hobbit, where they cashed in with 3 movies to the detriment of the story pissed me off. Other stand alone series (each movie is related but can stand alone) have met with mixed results, as to how many remained good. There,
Toy Story 1, 2, and 3 were amazing. Some series, only the original is decent (
Hell Boy, Thor). I acknowledge opinions may differ.
