I don't think it's inherently bad for Abrams himself to not have seen the show until asked to do it, but there's absolutely a good question of why the people that commissioned Abrams chose him, when he had no familiarity with Star Trek beforehand.

There is a weird thing that i think was hinted upon in a ds9 interview that for some reason “they” do not like to have star trek fans working on the set and those that where where supposed to act low profile about it.

I can kinda see how it can be both distracting to get work done and irritating or to have crew argue canon all the time (Henry Cavill in the wincher)

But i also can’t not see how political this might all be.
