Jyn, because even though I like Rey and we get to know her better, and as much as I like TFA, I just still don't like how Rey just catches onto the force and uses it like she does. Jyn feels more real to me.
I've never understood that complaint. The Force is not something that one learns how to use via an instruction manual. It is free flowing and mysterious it always has been. It's not like an RPG where one gains experience and learns more about it necessarily. Kind of like with basketball I had to learn how to shoot and have lots teach me how to become better, but I had friends that just picked up on it naturally and had no one do it and they were better than me.
Actually it's interesting to see how she learns, Rey is self-sufficient, that is her entire character, unlike Luke or anyone else she's a loner a survivor she has to learn how to do things on her own or it's death. Where technically even Anakin and Luke lived much more sheltered lives than that. Rey picks up on things quickly. And actually it's quite a long scene where she learns how to use the Jedi Mind trick. Because Ren is using it on her she slowly (with wonderful acting I might add) starts to mimic what he's doing, just as much as if someone picked up a basket ball and started to shoot it, and someone that has never seen a basketball before but may be athletically endowed (like my buddy) just starts to do it too but even better.
Rey mimics what Ren is doing and then tries it on a weaker individual then Ren. She's naturally endowed with the Force as the Luke an Anakin before them, but she gets to use it in more of a tangible way. She learns by doing while Luke who knows how he learned how to use it in Empire? I mean he force pulled a lightsaber and there was no one around or I'm sure any Jedi instruction books on how to do it. Using the Force I'm sure is not like step one crook your fingers this way etc. To quote Han "That's not how the Force works!!!"
Rey is self-sufficient and that's the entire point of her character. She's far from perfect though, she actually is more cowardly then Luke and continues to reject the call of the gods until the very end of the film. She's mind raped, beat to crap bangs up the Falcon something good running into everything. Stumbling all over the place when she fights Ren at the end.
But I just don't see the Force as some RPG where one has to spend a certain amount of time with it. I mean even Luke blocks the lasers with the lightsaber in like what 5 seconds of training? It's just never the way the Force has ever worked and it's no different with Rey. She is a fast learner she has to be, and she learned some of these things by others doing them to her or in front of her. That's how she learns. Of course she will need much more serious training as time goes on but like in real life some people are just faster learners, so in some ways Rey is much more flawed, and in others much better than Luke or Anakin.
So on the topic I love both of the characters but I will say Rey, she feels much more fleshed out and just a special character all around. Someone I think destined to become iconic herself.
