Positives:
-All the new characters are great. Totally on board for their journeys.
-So many great story moments and surprises throughout
-Great energy, humor, joy
-Effects, cinematography, etc.
-So many interesting questions moving forward.
Negatives:
-The Starkiller base stuff feels too divorced from the main plot and the main characters' motivations. Unlike in Ep4, the base isn't part of the message or the inciting incident, yet the shot of it exploding got way more emphasis. Felt flat, not satisfying. The moment of them destroying the shields needed to be more heroic or triumphant. Rey and Finn's journey in this movie didn't have a satisfying climax.
-Damaron hasn't had enough of a story with the main characters for his scenes in the attack to feel warranted, unlike say...following Lando in the attack in RoTJ. Damaron's role was very odd too. The movie starts with a lot of emphasis on the character just for him not to be a main one.
-Some of the comedy undercut some of Ren's menace.
-Missing some breathing room. The third act starts so quickly with the planning of the attack to Han lightspeeding straight into the base. Something about the editing makes lightspeed travel makes the universe feel small in a way the others didn't.
-Not enough new elements, ie: ships, musical themes, worldbuilding, setpieces (for example...Pod Racing).
-Some emotional beats felt like missed opportunities, for example not having certain characters present or reacting to 'the death'.
-Opening crawl or the movie itself could have set up the First Order / Rebellion situation clearer for the uninitiated who wouldn't understand why the Empire wouldn't have just crumbled away after RoTJ.
