What I care about is the writing itself and the acting itself. They didn't use their best actors enough. The movie should have revolved around them. It ended up revolving around characters that came of about as real as a politician. I thought the writers didn't create enough connection with the characters.
For example, Saw Gerrera was a foster father to Jyn, but that was barely explored. That was a missing for me because that relationship turned into a surface relationship. That relationship should have had more screen time and should have been a bigger part of the script. I felt that the characters were kind of one dimensional in their characterization. I actually liked the movie. I just saw different holes in the script. I just thought the actors had so much more to offer. They could have done so much more with what they had.
The Orson character was also way too plastic. Why was he the way he was? They didn't explore that enough to my satisfaction. It didn't make much sense. Why was he that bad? He didn't just wake up one day and start acting that way. And if he did, what made the dark side attractive to him? Then there were all these characters like Cassian or Bodhi Rook that were made out of cardboard. Cassian did absolutely nothing for me. I spent most of the movie wondering when they were going to knock him off. That was the best part of the ending-- spoiler.
To be honest the best character was Chirrut Imwe. Donnie Yen going off was great. That character was worth the cost of admission. K-2SO was a good character as well. All in all, they could have done so much more with that cast. And they didn't.
