So i just came back and here are my thoughts in no particular order (some heavy spoilers of course)
Life will go on if you haven't seen the movie, it suffers from a general badly planned trilogy (if planned at all) so it has the unenviable task of bringing it all together and giving it a good sendoff - something the movie doesn't quite achieve but also couldn't due to all the mess that came before.
- Using Palpatine was the biggest weak point.. he just appears out of the blue, corny villian twirling his mustache and going "Ha! It was me all along!" - it just doesn't work, at all. Abrams may have planned the end differently but since Johnson killed off Snoke like a chump he had to scramble and go back to well
- it plays it too safe - in the middle we are led to believe Rey kills Chewbacca by accidentally hitting his transport with Force Lightning - a mere 2 minutes later it is revealed that there were actually 2 transporters and Chewbacca survived
- Plot holes galore.. just one example: Palpatine manages to build a gigantic Star Destroyer fleet (seems like 100+ SDs). Where do the ressources come from and most important - the crews? The movie doesn't care and apparently only wanted the visual (which admittedly looked cool)
- The Force can now apparently beam objects across distances
- movie looks very stunning i have to say, great set pieces
- Chewbacca breaking down after he hears about Leia's death was heartbreaking
- they actually kept the appearance of Harrison Ford a secret! That was one of the cool moments (Luke reappearing as a Force Ghost was also cool but then again it seemed Hamill was always a little closer to the fandom than Ford)
Ultimately the new trilogy never managed to find its own story, it always went back to the generous source that was the original trilogy and using its elements to satisfy the fans. While it may have been ok for the first movie as a sort of transition they should have cut the cord with the next movies but didn't.
What killed the trilogy however was the apparent lack of true plan for the trilogy.. what does it want to say, what should the general story be and what was it about? New Star Wars should have taken a clue from the way the Marvel movies were organized and planned.. some things took 22 movies to pay off but when they did it was glorious.
The MCU approach may have been a little restricting for directors and creative writers as they had to work within the confines of the larger story but ultimately all the elements came together to form something larger.
So yeah.. i hope Disney learns from this and adapts. Find a true showrunner who maps this all out Feige or JMS style and keeps control over it instead of wandering off to do other things and maybe then you will have both a commercial and critics/fandom hit.
