I was kinda "eh" about Jyn until I read that post you reblogged where she describes Chirrut, Baze and Bodhi as "blind man, killer and coward" in the novelisation. That seriously rubbed me the wrong way. The Bodhi one pissed me off the most since he's anything but a coward, but reducing Chirrut to his blindness and seeing Baze as nothing but a killer also majorly shat in my cornflakes. I usually don't hate anyone in Star Wars but the more I learn about Jyn the more I start to really not like her.
I genuinely can’t get over that entire bit. You mix that with the way she acted throughout the film and you not only have a badly written character, you have one that’s just plain unlikeable. And I honestly would have been okay with that if there was a progression. If she had actually learned and grew from her first thoughts/perception of these people. But she didn’t. She really didn’t. She was propped up by the narrative as this badass, awesome, don’t-take-no-shit, woman. When in reality she was unlikeable, unrealistically naive, and just ugh. I’m just so mad because she had a lot more potential and it was wasted.
