I found the storyline to be above par and the interaction was excellent. I did not read into the film anything regarding SJ and there was nothing about the due that seemed homosexual. I have brothers in my beloved Corps that I have the same affinity for, would die for, and never could that be interpreted as anything more than brotherly love and respect.
Yeah, I fail to see how any of the characters in Rogue One were gay. I know there was a guy played by a Muslim who predictably defected over to the Rebels, but beyond that, not much. If you’re talking about that blind monk and his partner, they just came across as heterosexual life partners if you ask me. Even Luke and Han had a bit of that going on, and they’re straight (well, Han is, anyways, though even the Expanded Edition implied that Luke also was straight due to being in love with a farmgirl on Tatooine and having an alternate reality where he DID in fact marry her.).
And as far as Jyn Erso, I actually could tolerate her a LOT more than Rey, to be honest. At least she doesn’t insist that she doesn’t need rescuing and actually has shown vulnerabilities in the film, not to mention at least she doesn’t come across as doing perfect at everything she can get her hands on (granted, I did sympathize with Rey at one point, only one point, and that’s her first appearance where she’s pretty much a junk dealer fending for herself, barely even managing to get much payment for her work, and it being revealed that she’s waiting for her parents to return as they abandoned her. Unfortunately, they lost me when she started doing everything perfect on the first try starting with the Millennium Falcon). Plus, I’m a bit of a sucker for family values stuff, so even though I don’t root for the Rebels anymore (you can blame Lucas’s bragging that be based the Rebels on the Vietcong and the Empire on America for why I don’t root for them anymore), I can’t help but at least be sympathetic to Jyn Erso. Long story short, I didn’t find Jyn Erso to be a mary sue at all, unlike with Rey.
