"Annihilation" Wins Nebula Award: Really?

Yeah, it seems so: official Nebula Award page here.

I mean, it was alright (here's my review from last month), but it wasn't that good.  On the other hand when you consider the competition in today's sci-fi market, maybe it was the best new novel at hand.  It's a common lament, as has been noted here in the recent past.
