Saw this today. 1/3 poor, 1/3 average, and 1/3 great.
1/3 poor: One third of the film felt like it belonged in the spinoffs, like pointless dialogue, pointless attempts at humor, and pointless awkward pauses or one liners. (some of the humor was ok, definitely not all)
1/3 average: One third of the film was average, meaning it was neither better or worse than what you would expect from a modern film in the Star Wars franchise. (Around TFA quality).
1/3 great: One third of the film was great - but it's not a good sign that some of the great parts had the benefit provided by nostalgia, using actors/characters from the original trilogy who are being killed off and wont be involved with this franchise anymore.
This film was more ambitious than TFA but TFA felt more refined and polished mostly because almost every scene and line of dialogue had a purpose. IMO Disney shouldn't have been pushing for a yearly release alternating between the spinoffs and the main series, doesn't allow enough time for polishing, quality assurance and re-shoots if necessary. In the short run it makes them more money but in the long run it's going to end up with audience burnout and lower quality of releases.
