Seriously, it's just flawed. I said earlier, if you're asking me to watch a movie about a suicide mission that's just fine with me, we don't judge war and horror movies on how many characters make it to the end and telling tragic but heroic stories works.
But, when that's the point of your movie you need to make us feel for them. Maybe some of them aren't super cool with dying, maybe they're scared or don't all do the right thing like robots. Everybody in this movie starts wherever their "diverse" background says they start, immediately discards all elements of their personality that aren't useful or witty, does exactly what the script needs them to, goes "what? oh no, I guess it's my time" and then die basically back to back with these sort of tonally identical slow camera moments (which there are too many of). The "conflict" between characters is usually talking about how they don't understand each other cosmetically, but it doesn't really impact things.
Of the main characters, the girl is again played like someone who had their background told to them in an open world game ("you're a tough girl, in and out of prisons and whatever and blah blah rough life because of the Empire") and then just hits the Paragon option on all the dialog. Her mood shifts really fast from potential wildcard to self-sacrificing hero, and when she does the guy just sort of follows.
And I'm not saying George Lucas invented the rogueish anti-hero, or calling for an embargo on one across movies like Star Wars did it first, but when you have Han Solo
in your universe it's going to draw comparisons and you might want to consider doing something to differentiate yourself and I think the main difference between the two was that we saw the other guy kill somebody he didn't have to kill (and Han shot second
). Smuggler turned rebel hero for the main female protagonist was a good arc over three movies because it was earned. This guy goes from "possibly even sketchier than Han Solo" to "pretty much guaranteed to help and be super supportive" pretty early and doesn't believably waver.
