Funny thing. Sith's training is "complete" when he kills his master and takes his place.

I don't like using other lore in the Star Wars universe for the movies, but really strong force users can 'commune' and use force abilities to increase their reflexes, reaction, speed etc.

I don't know if that is what they were going for, but at the end when Kylo was doing his "I can teach you" it seemed like she closed her eyes and let the force itself take a stronger hold in her. That coupled with how wounded he already was and most likely very mentally fucked up after killing his father, I was satisfied with how it ended. A lot of other shit annoyed the hell out of me in the movie though.

Take Naga Shadow for example, made a star go supernova using only the force.

Considering the fact that they are related, their potential would be the same. Kylo is bloody inexperienced though. Granted, more than Rey by a considerable amount, and yet he is still a novice with great potential himself and he was wounded physically, and perhaps mentally. Also no, the training doesn't just make you a superhuman all the time, it takes skill and concentration and it lasts for a short while - thus it is a combat ability that only strong force users can use in combat.

The rule of two. Meaning that there will only be one master and one apprentice, where the apprentice is supposed to always try and overcome the master, to grow stronger, and in doing so, makes sure the master stays strong(er). Fuck that there's only two sith in the entire galaxy at any given time, shit is so fucking stupid and utterly ridiculous.

Yes, of course he had more training - It's bloody naga Shadow. Point was that with just force alone he made a star go supernova once, during the great hypserspace war when he was 'defeated' and headed back to Korriban.

I never said she was as good? Luke had a child of his own with someone else, obviously. Her reaction to touching his saber and that awakening her properly: 2+2 = 4. Put it together.

Are you daft.

I said given the situation and the fact that he didn't want to kill her but make her his apprentice, and that she used the force at the end made it a good result/conclusion of it.
Yes, they are able to react well - but they are not superhuman all the time, they need to use the force to jump higher, run faster and the like, and it is not limitless. That he is able to do something he was taught and trained to do is obvious - don't know why you're bringing that up. He didn't lead shit, he took orders, no one there respected him worth fuck-all, just threatened by what he could do.

There are different rule of two's, there are one ridiculous one where it's meant to be just two grand siths and no more. Then there is the one where there are several, but restricted to groups of two - one master, one apprentice. Sometimes the apprentice is sent to another master for a mission (making them 3 for one mission), sometimes two masters and their apprentices team up. But always just one master, one apprentice as you said, to avoid them killing each other all the time to grow stronger - and ultimately just making the sith empire weaker.

Making a star go supernova =/= being able to channel force to heighten your battle capabilities for a little bit. Come on now man. I'm out, you have a major fucking hard on for Kylo and for some reason hating on Rey, can't deal with people like this.
