I don't really think the lighting bit is relevant, seeing as it's a Force power as well. Yoda not only had to redirect the bolts themselves, he had to mentally fight the user casting them. Force Lighting is a very high level Dark Side power.
I think that the main point of Kylo's blaster bolt trick was, ultimately, looking cool. Indeed, in light of the rest of the movie, I think this might have been one of these scenes (there were more like that) which were visually impressive, but the implications weren't quite thought out. It clashes with what we're shown afterwards.
Also, logically speaking, it just hit me that it's
stopping a blaster bolt that would require a lot of energy expenditure and concentration.
Keeping it there afterwards would be a trivial trick of little utility. Could Luke levitate a bullet-sized object and hold it in the air during his early days? Probably. This is no different, aside from the initial effort it took to actually bring the bolt to a halt. The motive force is applied to the bolt as it leaves the barrel. It's no wonder Kylo could walk and talk with this thing hanging in the air. It looks to us like it
should spring forward the moment he lets go, but it shouldn't. He didn't freeze time, he froze the bolt. He would likely have to put some effort into stopping it from dissipating (talk about showing off...), but that's probably not very hard, either. In light of the above, what he did was a
totally pointless show trick that seemed mighty and awesome to everyone who didn't know its workings. That's Kylo Ren, all right.
This is also why we didn't see it earlier. Other Jedi might have stopped bolts as well, but if they did, they let them drop and dissipate afterwards.
Note that the above is an example of "fridge brilliance" and thus isn't really a plus. When you think "Hey, that scene
does make sense after all." the next day (or two...) after watching the movie, this still means something went wrong, just not as badly as you thought.
