Star Wars: 10 Things You Learn Re-Watching Rogue One
4. Jyn Erso Is A Terrible Protagonist
From the very outset, Jyn is nothing more than a blatant copy of Rey, only with none of Rey's likability and personality. She is just the typical tough woman stereotype that fills today's action films, and with her just acting like a stroppy teenager throughout, the character is a tragic waste of Felicity Jones' talents.
There simply is no development to her at all and her only 2 emotions are being sad or being annoyed by something. The film jumps from her as a child watching her mother being murdered to her as an adult in a prison camp with no explanation of what happened to her in the years between.
The only things the audience finds out about her are when Saw Gerrera left her and her list of criminal offences- which are literally read off by another character. Perhaps the film's writers haven't heard of 'Show don't tell' which is one of the biggest movie rules there is.
In fairness, it's possible Jyn might have been fleshed out more in previous versions, but this was then left out due to the heavy reshoots that were otherwise well hidden.
