Took the boys to see it after school on Friday. Although I enjoyed it, I thought Kylo Ren was about as intimidating as a petulant teenager, and couldn't help thinking that a few more smacked bottoms as a child would have saved the galaxy a whole heap of trouble. I heard an argument at work over his petulance/intimidation It's almost deliberately shown by Poe he's not intimidating him, but he's quite powerful. There could be an age bias thing, as when a young man goes into a lightsabre flinging rage and then calms right back down to say "anything else?" he is seen as a young man having a strop. Add 10-20 years onto him and you don't have to do anywhere near as much to be branded "unstable". My own thoughts are the story did well with him. It shows him as being all powerful at the start, then progressively we see the fear and confusion that rules him, and ends with him shown to be powerful but untrained comparatively speaking with others we've seen in the series. So he has a lot of room to grow, and I suspect in the next movie a year or two will have passed and if done right we will see some deep development. I've figured out who Rey is I think. Won't post here, will only pm that as if it was right I'd take a big revelation out of episode 8 haha.
