Abrams is NOT a good writer. He and Damon Lindelof are horrible writers! They will introduce things to a story that they have no plans on explaining down the road...Abrams refers to it as a "mystery box". That is lazy writing at best which leads to ****** stories by the end.
The best example is Star Trek: Into Darkness. Kahn blows up a building, then transports himself to the Klingon homeworld. Interesting visual, but why does the Federation now need to spend billions of dollars on Spaceships when they could just transport people to practically anywhere in the galaxy? Also, did you notice how the transporters on the Enterprise would stop working at just the right time that they couldn't beam anyone up....but they sure could beam them down with pinpoint accuracy on moving objects! That's is poor writing because they do not take the time to "live" in the universe they are creating. There have to be rules to follow, and if a rule is broken, there has to be a valid reason why that rule was broken. This is effort that Abrams just does not put into his works.
JJ Abrams makes incredible images on film (that establishing shot of Jakku with the downed Star Destroyer is still incredible to look at), but he is a lazy writer and potentially good works suffer because of it.
