Kylo killing Snoke was a bad decision IMO. Though Snoke was a Palpatine ripoff in TFA, he had so much potential to be made into a more unique character given how TFA revealed almost nothing about who he is and what his backstory and motivations were, and Rian Johnson threw all that potential away solely because he saw the interrogation scene and thought it’d be cool to focus on Kylo.
A weak writing decision moreso to me based on how I think Kylo not being anything of value as a character or villain rather than Snoke having much of a point. As is, at least Snoke had presence to him. Kylo taking over neither adds to him as a character neither does it change the first order as far as TLJ shows us I think, he just seems to keep on doing what he was doing before and FO does as well to me, only difference is that Kylo’s dumber to me and more petulant, so who cares and what’s the point? Another empty RJ attempt at doing something kinda different and then just not actually doing anything different with it to me.
Like Rey nobody. Not as different as I think the movie thinks considering every single Jedi in the PT, barring Anakin, was never developed to come from a special bloodline, but still, I think there’s room to expand on the character within that idea, yet RJ just seems to use it as a vague way to have Rey be kinda insecure and force reylo to happen for no real much character or story reason for me. Rey has to be told by Kylo that her parents sold her, and she’s sad for about a minute and in the scene after when she’s flying she’s all hunky dory.
