Going into this i thought there was 2 ways in which the movie could be a disappointment, the first was they could have fucked the premise, they needed a way to throw off the balance the balance of power to make them rebels again, I thought they did this well enough. The other way was for there to be no real closure, this was also avoided by sticking to 4 so closely. Avoiding those two problems definitely made it a solid movie.
~radical opinion part here~
I felt as though by sticking to 4 so fuckin closely it killed the movies chances of being incredible, once i clued in pretty early to the fact that i was watching 4 with some fresh faces there was no more chances for me to be amazed. I felt as though by feeding into this nostalgia they were taking a conservative approach. I realized Han was going to die about half an hour before it actually happened just by following 4.
There were real positives though, I thought the new characters were managed very well, both Finn and Rey were well done and i thought Ren was very well done, he had the same amount of depth that you'd expect of a sw villain that isnt maul (unless you count clone wars i guess). I think this movie will be remembered by how well the next two do, and I certainly think 8 cant be as similar to 5 regardless of how erect people get thinking of 5. They've got peoples attention and reinvigorated a passion for sw again, now they need to do something with it. 8/10
This also really reminded me how much I love the old republic era sw as well so thats something i guess im off to play kotor
