Re: Last movie you watched
I disagree. Cassian's arc was indeed the most robust, but it's much more than "kill dad"/"won't kill dad". He starts out doing the Rebellion's dirty work, maybe not happy to do it but realizing that it needs to be done. (Shooting the informant at the start; watching it on Blu-Ray I realized that Cassian knew that this guy was dead the minute he said "Erso", because he couldn't risk the Empire getting their hands on what he knew.)
Over the course of the film, he falters - yes, grows a conscience. But add to that him feeling betrayed - he did so much work for the Rebellion, and when it's time to make it absolutely count, for the Rebellion to mean something, the leaders of the Rebellion turn their back on him and don't go for it. He says something along the lines of, "If this doesn't happen, all of the horrible things we've done in the name of the cause were for nothing."
From someone who'll follow orders to do bad things, to questioning orders to do bad things, to downright going rogue (no pun intended... mostly) to do the thing that his orders don't have the balls for.
Jyn meanwhile goes from not caring about the cause ("How can you stand to see the Imperial flag?" "Can't see it if you don't look up.") to spearheading that cause when others didn't have the courage to. Yes, she does it more out of respect for her father, at least at first, but she realizes the importance of what she's caught up in.
Saw, I agree, was mostly wasted. Knowing there was more of him shot makes me wonder what it was, but since the release was so stingy with special features (no deleted scenes at all for a release that was saved in massive reshoots and reedits after the fact) it's hard to know what that might have been. He was serviceable.
Bodhi had gone through his arc before we see him, Chirrut and Baze generally don't have an arc and are there to round out the team and keep them on track. K2 discovered Friendship or something. I still enjoyed the characters and they all were worthwhile in the story, IMO.
Of course, Squiggly, I'm sure that you'll disagree with me and say that I'm reading too far into it, where I could come back saying that you need to just pay attention. In the end, you didn't enjoy the movie, and no amount of, "Um, actually," will change that. But on this one in particular I felt I had to speak up.
