What did the writers do and who did the Editorial?

Rating: 7/10 (14 December 2017)

SPOILER ALERT!
Snoke was a Sith Master, right? When I saw the scene unfold, in which Snoke perished, I was aware of the Lightsaber at his side and I knew Kylo was looking for a way to betray his master. To be able to sense that, it suffices to be human. I didn't need to be Force sensitive, let alone be a Sith Master. Oh boy, this was as worse as it can get. I hope.
There're other failures in the screenplay. Other reviewers pointed some of them out already, so I'm skipping those.
Just for the record: I'm a Star Wars fan! I'd like to remain one!
