I thought there was entirely to much time spent on side stories. It felt a lot like a reset. Almost everyone from the past is dead and the entire rebellion now fits in a conference room. The other problem is emo Vader is just not menacing enough and the other problem is he is still more interesting than Rea. They should try letting her show a few more emotions and maybe have a few more lines, I think the droid talked more.
I rank it fifth in series as far as likeability.
New Hope
Empire Strikes Back (yes probably better than New Hope but I was 12 when New Hope came out and it will always be first)
Rogue One
Return of the Jedi
Last Jedi (if I actually watched ROTJ again they might switch)
Force Awakens
Clone Wars and the other two sucked to hard to get rated.
