All this talk about not caring about the new characters does have me thinking. I absolutely care for Rey, not even so much as to her mysterious past but I genuinely like her. She is played by a likable actress, I always enjoy the character who comes from humble beginnings, and she is being thrown into a conflict she never prepared for.
Finn....I just wish they would have wrote him differently. He could have been a very interesting bad ass type of character who knows how dangerous the First Order is and not automatically be the comedy relief who is out of his element. There was so much wasted potential with him. I am very curious to see what Rian Johnson does with him though because he has a knack for getting to the heart of characters and fleshing them out (see The Fly episode of Breaking Bad). So maybe Finn will become more interesting.
Poe I am curious about also. He was a non character to me. I wanted to like him...he just didn't show any real interesting characteristics other than being a nice guy who is a "hell of a pilot"
....I hope again like Finn, Johnson fleshes out his character more.
I think the biggest problem was that these characters automatically became best friends and there was no room to flesh out their relationships between each other. Han and Luke didn't like each other at first, it was a friendship that was earned. Same with Han and Leia, their relationship grew over 3 films and was all the better for it. The new "man three" meet, like each other, go off on adventure together. I want more drama. Anyway, I really hope interesting events happen to these new characters. Because right now, I really only want to find out what happens to Rey, Kylo Ren, Luke and Leia. And of course find out who the hell Snoke is.
