Well, Cassian has a personality as well. He’s an intelligence officer, his job is to have no-man’s personality. He only reveals his emotions when he knows his fate is sealed.

And that’s why I called him a standout character in a group filled with underwritten ones. It’s a shame that we can only talk about Cassian in depth. You can’t do that with any of the other characters which is why the characters fail me so much in Rogue One. I have to know who these characters are before I can invest my emotions into them. We knew plenty about Luke, Han, Leia and that in conjunction with their chemistry makes them fun and interesting characters. We didn’t even get any chemistry from the Rogue One crew. Finn and Rey along with the Finn/Poe bromance shared the same spirit of comradery that was present in the OT but was strangely absent in Rogue One. I would have been perfectly content had Rogue One done one of these things right but how these characters are written doesn’t grab me like the OT and TFA’s characters do. And having sub-par characters in a Star Wars movie is wayyy worse than any amount of rehashing in my opinion.

Why do all heroes need to choose to go on their journey?

You got this exactly around.

What? lol
