Woah.. hold up with the spoilers there!!!
In fact if you haven't seen Star Wars yet.. do not look any further.. I'll be mentioning a few other
SPOILERS in this post...
So in reply to your response.. yes.. that will definitely be the main focal point of the second film I'm sure...so we know that the force awoke when she first touched Lukes lightsabre (ooh errr)... so I imagine Luke will have the answer to that.. but obviously we'll have to wait for his explanation...
There were a couple of things that got me slightly riled.. Kylo Ren related mostly... I thought he was a great character.. but he's had training from Snoke for a few years (lets say).. and he can't *easily* beat an untrained storm-trooper in a lightsabre fight.. granted Ren is injured at the point of the fight.. but that's just bollocks. I'd give Rey the benefit of the doubt as like I said, I'm sure things will be explained... but when Ren does slice down the back of Finn.. how does that put him in a coma.. he should be sliced in half and brown bread!
Also, I found Leia's character very underwhelming.. given that technically she should be a Jedi Knight in this film.. yet nobody gives a shit about finding or killing her.. its all about Luke.
