You can't make the argument that because we've seen a grand total of some 3 hours worth of Jedi moves in limited scenarios we've seen every possible permutation and use of the force in every scenario.
There probably are limits to what Jedi can do and so far, we haven't seen ANYTHING that goes outside of the loose boundaries we've seen. Especially considering we have a clear example of Vader manipulating a blaster bolt after it's been fired.
Point is; if that bothers you, then cool but don't act like it's breaching some strict rule of the Star Wars universe and therefore ruins a part of the movie. Since Kylo had his ass handed to him, clearly there are limits. And since we don't know what Rey's back story is, we don't know what her capabilities or limits are. Based on her flashbacks and the voices she heard, seems like she's had some training she didn't remember, or was made to forget.
Also, it's the first time we've seen force users trained outside the norm. That could very likely change things.
I don't know how many hours of Jedi moves we've seen to be honest, but I do know we have seen the best force user do a number of things in life and death situations. Perhaps even more importantly, is what they didn't do in some of those situations, which has to do with their limits. I wouldn't say this is the first time we've seen force users train outside the norm either, because Luke was the first. Most Jedi started their training as children and it took them decades to master their abilities and many years to achieve the rank of Jedi master. Even Anakin, as powerful as he was, never achieved that rank, something Luke sort of achieved (but not really) with unconventional training and within a short period of time, since he began his training as an adult, which is why I say he didn't official achieved that status because there was no jedi council and the way he did it was not the traditional way.
It's true that we don't know about Rey's past, but until we do, I'll judge the film for what it is, not what other films might or might not add to the story. There's a lot of things this film doesn't explain, and expecting the next films to answer all those questions is wishful thinking, imo. Like I said, if in the next film Luke says to Rey that she's the best ever or something to that effect, fine...I'll accept that. Until that happens, I do think Rey using jedi mind tricks and becoming an effective Force-user in a few hours, when it took Luke Skywalker a few years to master certain techniques and abilities isn't very consistent with the film canon, since at least Luke had some guidance and first hand knowledge and experience with the force because of Obi Wan.
As for Kylo Ren's abilities, his powers like most jedi and superheroes are a bit inconsistent because the plot imposes limitations when it's convenient, like him having the ability to sense people and know their location, but when Solo was near him, he couldn't sense him or for that matter Rey, when she escaped. Still, his abilities were pretty impressive for someone who was not a sith or a jedi. He could do things like obtaining information from people's minds, something Vader didn't use on Leia when he wanted information, or even in the prequels, some of the best force users didn't show those skills. I still think the way Kylo sensed Poe's attack with his back turned Spiderman style, and then in less than a second stopped the blaster shot in mid air before it even got close to him, while simultaneously freezing Poe, was very impressive for a non Jedi/Sith, and again something we had not seen done in such a way and with that level of difficulty by Jedi masters or sith lord in previous films.
