OK, so obviously the biggest thing that's going to be going around is that they killed off Han Solo, which is awful. Because Han is an awesome character. I had been worried because I'd seen someone on Facebook write "I can't believe they killed Chewbacca" I was annoyed but was also hoping that it was written as a joke as I'm sure they knew how big of a deal spoilers for this movie are, and then I saw Simba04 post how he wouldn't be seeing any more of the movies because he was watching them for one reason. Then I knew that a major character had to die. So that in itself was a spoiler for me, even though it's not technically a spoiler. In regards to Hans death, while he is my favourite character. I feel like it happened in an acceptable way, and not just some random firefight. So in the moment it's not wholly unexpected.
My only real gripe with the movie was the lightsaber fight between Kylo Ren and Finn, and Kylo and Rey. Kylo is meant to be well trained and they quite easily get the upper hand on him several times. I know he's wounded, but it seemed like a bit of a miss-match to me. My other concern with Kylo Ren is that he looks nothing like either Han or Leia, which is just irritating
I have my own theory about Rey's origins.
Overall, the movie had a great feel to it. CGI was extremely well done, and everything felt believable. There's a lot of great cameos from old characters which is wonderful. I felt the script was good, although as Pat pointed out to me after the fact, the plot is rather similar to that of A New Hope. It works, but really the giant death laser planet is a little excessive. With the amount of manpower and funding it must have cost to build, surely they could have an enormous fleet that would be just as, if not more powerful.
