Overall I enjoyed it. There were a few things that didn't make sense to me.
Rey was never trained in the force but could read Ren's mind, know that the force could be used to control minds, and control the mind of a stormtrooper.
What is up with R2D2? He switched off, but then just happened to switch on and have a nearly complete map?
Ren has force ability to stop blaster shots, but can't force grab his lightsaber from the snow?
Wonderful the ways of the Force are.
If the Force wants to have a new Jedi all of a sudden - it just happens. Its what the Awakening is about.
Is that what happened to you? You just awoke one day and had force powers? It took me 13 years of public school, four years of undergrad and two years of grad school and I still can't force fetch my beers.
