Here are my issues with it...
1. Capt Phasma was a massive letdown. Looks completely badass but gets taken prisoner and never fires a shot. What a waste of awesome imagery even if she comes back in the next movie.
2. Stormtroopers are no better soldiers or pilots this time around. Just drop like flies vs. anyone.
3. Harrison Ford was simply too old to be in the story. Sorry but I couldn't get past it.
4. If Fin was raised from birth to be a stormtrooper, why did he fold before he even fired a shot? Just gave up. Needs some back-story.
5. Did the First Order really let 5 people destroy their entire base? Thousands of troops but not a bit of defense against a few lightly armed rebels.. Come on..
But those are small compared to the biggest sin committed by this movie... HOW THE HELL DID REY DEFEAT REN WITHOUT A BIT OF TRAINING??? She picked up Luke's lightsabre and beat a trained "Sith" like she's been trained from infancy. She was able to use the power for the force without a bit of knowledge of what it is. That alone almost warrants a thumbs down.
Ren is going to turn out to be someone’s daughter.
The others didn’t surprise me much.
The last point looked great but required deliberate & almost painful suspension of disbelief. I get that she’s a natural, but still did too well against a rising Sith Lord. Granted, he’s a sniveling brat.
Ford was old (needed some Grecian formula for that less grey look), but I did get past it. What I could not get past was Carrie Fisher. Talk about not aging well...
