I truly think that based the evidence in the first movie and some very obvious instances that Finn was going to be a jedi. Folks have been trying to explain away him hearing people's scream before they were blasted, the fact he not turned on, but used a lightsaber without killing himself, and finally the impulse to leave the first order instead of killing. Now with the new movie there are clear moments that display his force potential. I think that it's sad that someone really worked to alter what I think have been his true destiny just to make Rey the central character. I'm wondering what is so bad that they couldn't have made them both jedi through the whole trilogy?
