I agree, very little content shown. What plot was shown was basically "legends fighting one another for no readily apparent reason (well, Chekov's family was killed, but that's it). Oh, and I'm not a fan of the backlit letters, but that's just me. I'd rather text in a trailer be understated rather than overstated, but YMMV.
Effects look good, though, and the brief glimpse of the sets look pretty nice.
And, while I'm musing idly about it, I think I would've gone with more of a ramp-up. The music, graphics and everything else are screaming conflict from frame 1. If the concept of these legends fighting one another is supposed to be surprising (I'm guessing?) then it'd work to have either a) a ramp up to the conflict or b) a 180-u-turn where you lead it up making it seem like they're working together (including clips, don't use text exclusively for the first half of the trailer like that), including peaceful/thoughtful/reminiscing music, *then* throw the curveball.
But again, YMMV. This is just me thinking aloud, and as with all art, it's just MHO, so please don't think I'm saying it's all wrong or anything lol
