To be fair about Rey's use of the force so quickly. They did address it, albeit not directly. Snoke even said to Kylo Ren - "There has been an awakening.." and "Even you are not ready for this..." or something along those lines.
Why would he think Ren isn't ready for this awakening unless he can tell that Rey is incredibly powerful with the force. If she was just a regular force noob, I don't think the two of them would be that concerned.
I agree, it seemed slightly contrived, but this is a movie, not a history of the force and its use - and they only had slightly more than 2 hours to tell the story, so I can forgive it.
