Even fictional worlds have to have some internal logic to them, or else the character stories become meaningless.

In 'The Force Awakens', the plotting was weak, but at least it still felt like a 'Star Wars' movie, in the sense that it respected the previous movies and the 'Star Wars' canon.

In 'The Last Jedi', all plot coherence is lost - it felt like a 'fan fiction' where they tried to throw out the entire canon in pursuit of something new and original. But it didn't work, because there was nothing 'grounding' the characters - the things they were saying and doing just weren't making sense given the context of the rich history of 'Star Wars' - you can't simply pluck favourite characters out of one particular world (or context) and deposit them in an entirely new one.

It seems that they were definitely trying to remake 'Star Wars' to emphasize political correctness and strong female characters , but this destroyed the coherence and logic of the 'Stars Wars' narrative.
