My primary issues are as follows:
1) The fucking shields. Poe had to be tortured by the force to reveal BB2 to Kylo whereas Phasma basically just said fuck it with a blaster to her head. A hard nosed fuck it all Stormtrooper commander gives in at the sight of a Wookie. Ugh, even Brienne of Tarth and Commander Lyme are ashamed. Let's not even consider how ridiculously quick they found her given the base is supposed to be the size of a planet.
2) How Finn just finds Rey running around on the death planet. Need I remind you how the base is supposed to be the size of a planet.
Wouldn't it make much more sense if Finn found Rey randomly (because it'd be funny), and she force persuaded Phasma to put down the shields? Seriously, ugh.
3) How the fuck does Kylo Ren, who's presumably been trained by both Luke Skywalker and Snoke, and who apparently managed to kill hundreds of Padawan's ala Darth Vader get his ass royally handed to him by Rey who's basically a force virgin who didn't even have an Obi-wan Kenobi to make her swing a lightsaber around blinded?
Look I get they were trying to play him off as an amateur as well, which is kind of cool (two amateur jedi's going toe to toe and causing ridiculous amount of havoc because they are uncontrolled would be baller), but this makes no sense. What should have happened is that a pissed off Chewbacca flies the Falcon up and blasts a Kylo Ren who's about to kill Rey, leaving some baller scars for episodes VIII and IX.
4) The chick hero passing of the torch scene. Two characters who don't even know each other hug like old friends. I get that Leia is supposed to know about Han because of the force and Rey was sad (because they poorly set up Han as the father she never had), but the unspoken hug was stupid. Maybe this will make sense later, say if Rey ends up being Rey Skywalker.
5) The pacing of the final battle, the character Poe Dameron, and all that nonsense was stupid. I can't tell you how pissed I was that BB2 didn't decide to stick around with Rey. Now she's stuck w/ R2D2. I don't even want to get into how convenient it is that he woke up. Maybe this will make sense later too if Luke chose to be found at the end of the movie.
Minor fixes and I'd be wet. Now I'm just meh about my childhood favorite movie series.
