Personally speaking I didn't mind the movie too much, but I really don't like Rey. Specifically I don't like how the character had zero explanation as to how she got as good as she did. The understanding of how to fix a ship was sort of (and I heavily stress the sort of here) understandable given that she made a living off of salvaging and what not, so it makes sense that she might fiddle around to see what did what in her spare time, but the piloting was brought in out of left field since she not only unfamiliar with the ship she's piloting, but she's messing around with a ship that required two pilots, one of which happened to be one of the best around. Then there's the whole "using force abilities with little effort with no prior knowledge of using the force" thing which really grinds my gears. I'd be fine if the movie gave us at least a single glimpse of her doing something that would at least partially explain her abilities like we did with Luke.
