The movie needed 30 minutes more, and it needed most scenes to have some room to breathe.

The same editing issues were there in TFA but because the story was so straight forward people overlooked it. But TFA rarely let’s the scenes breathe, its go go go from the first scene.
And that can be a good thing for some movies, but JJ did the same thing with Star Trek.

Compare JJ’s Star trek movies to the third one in his continuity, it’s like night and day. The third one let’s the characters have moments, so overall this is a JJ issue and a trait of his.
