I guess call me crazy but I just legitimately don’t understand the “lack of cohesion” complaints. The two films are different, sure, but not anymore so than a second part should be. I feel like the ST is well on it’s way to being a very cohesive set of films telling one story across three films.
I think, for example, the difference between TFA and TLJ is far less drastic than, say, the difference between Batman Begins and The Dark Knight. And I think it’s about on par with the differences between the original Star Wars and The Empire Strikes Back (this is something that can be really hard to wrap your head around if you only ever knew them together - I can attest to this from experience).
