1) He was not clued in or stable due to killing his father. How could you not see that in his expressions / emotions and the movie had just shown numerous times how powerful the crossbow was... as in far more powerful than other blasters.
But you don't know that. There is one thing that he couldn't choose on which side he wants to be and he chooses on this platform killing his father. But there is another explanation for this: he knew what he wants to do and he was playing, luring Solo to come closer. I don't know if this moment should be very plain or not but it doesn't matter. I never saw Jedi/Sith died like this or get a shot. Now, someone would like to think that he didn't defend against this shot for a reason, to punish himself. It doesn't matter. The story lacks reasoning. If Chewie saw him taking a shot already, why didn't he finished him in the first place? There wasn't any better chance to do this. It's another silly thing in this. Oh, I shot him, he killed my best friend, now he's bleeding, cool, that is enough for me, let's head to the ship and forget about what happen. Stupid things happened throughout the movie but no one seems to care about it. I am speaking about the storyline... it wasn't good. To many things happened by chance. Actually all of it... And tell me. If Ray was so strong with the force, why she didn't use it before, but just let him trap herself. Things Kylo Ren did before doesn't allow me to think that he wasn't properly trained. We've been there and we saw what he was capable of doing. Power of the blaster has nothing to do with it. It's about the force and focus. Besides, if the Crossbow was so powerful, then it would blast him off of that ramp he was standing on, like it did with the armored stormtrooper before. Again, lack of consistancy. The only reason he was shot in my opinion was to make his fight with the others more explainable. Just to let you think that he was wounded (he didn't seem to be to be honest) and so the fight would go according to what they visioned for the storyline, so they had an excuse. And that is a bad written story too, to look for excuses in the least appropriate way. So, I need you to ask yourself, maybe you didn't pay attention. I love STAR WARS and I will forever. But I care about it even more now, because I truly believed that no one can make it so uneven and unreasonable.
2) It didn't just happen. She touched Luke's/Vader's light saber and had the vision. She was told how to listen to the force. The trauma of being force mind raped by kylo ren all pushed her to begin to feel the force. Luke started the same way when he started to deflect laser shots in the melinnium falcon with helmet on or anakin as a boy and his reflexes during pod racing. No different. Lastly, kylo ren is no master. He's not 'properly trained'. That was evident in the movie more times than can be counted especially at the end when it is explicitly stated.
ya'll people are just not paying attention.
Yes, my friend, she had a vision. I don't like that part at all. I don't like the fact that she touched an item and she had a vision. She didn't need to touch anything, if you asked me, to had a vision. But I won't focus on this, it's a minor thing. I love Ray, she was played by great actress, so natural that I'd love to see her again in STAR WARS and I will. But it's not her fault that the story was weakly composed. Luke had a Master to train him. And remember, we don't know how often he had those trainings with Obi One, and how many lessons about the force. The movie doesn't show everything. And after trainings he didn't use the force at all. He did it only with the help of Obi-One when shooting to the Death Star. He was influenced, he had him by his side through the force. Ray didn't know nothing. Didn't experience anything like this before. Anakin never used force but only his relfexes. So I won't go any deeper into this, just to say it WAS different case scenario. And Kylo Ren may not be a Master, I bet he isn't, but you cannot say, after wat you did see in the movie, that he wasn't properly trained. You saw what he was capabe of doing. And that's pretty it.
My friend, I wish that this episode VII would do it for me, and I was actually sure that it will be amazing. But I am disappointed. I could forget about all the things that annoyed me but again, I like to be true to myself. I saw what I saw. He played on us, tricked us, used those little bricks of nostalgia to build the wall behind which lies ignorance and lack of story. I wasn't expecting that for sure.
I really care about STAR WARS as I said before, that's why I won't remain silent on this.
