I agree all that except the third one, Chrono. Come on. The emperor wasn't hanlded the best in the OT so that makes it okay to handle Snoke poorly in the sequal trilogy? It doesn't fly with me and just feel like an excuse.
I'm not saying the Emperor or Snoke were handled poorly. I'm observing that the Emperor was an even scarier Big Bad Guy than Darth Vader, the same way that Snoke was a BBG compared to Kylo Ren. I'm stating that the OT didn't explain the origins of everything ad nauseum, left it open to interpretation, and benefited from leaving things vague.
OK. I agree the OT benefited from that but I don't think that's the case here. If they put a line in there showing that Snoke knew that Kylo would kill him, to the point where he's fine whether he kills Rey
or him, and it sort of does, I think it would have gone over better. There's been talk that Sith take over leadership by killing their masters but the movie doesn't recognize this much less mention it. If they had Snoke smile and say,"Good, good. Your training is complete" before he dies from the saber, it would have gone over MUCH BETTER for me. But as is, it's left
far too open, far more so than the Emperor in the OT, to the point where it just gets a shrug from me and doesn't lead to anything truly interesting. That would also show to Snoke's guards not to fight them because Kylo is now the rightful heir to the throne, as he has killed his Sith master, but that wouldn't allow the wonderful fight crescendo scene. So
I think there was potential there but they flubbed it and really, all they needed was the one line and they fucked even that up.
