They didn't show a single actor from the main cast
Its a TEASER - anyone who had expectations that they would see any or the main cast clearly doesn't grasp what teaser trailers are for...
As for your other issue that's all about opinion I'm sure. I don't think we were supposed to get a "glory shot" for this by any means.
If memory serves there's almost always a starfield involved with Trek teaser trailers, and for Trek VI there was a projection on the Enterprise of past adventures from film and tv. That one also seemed to stand out in that it was different then most teasers. Trek II's I think was a voice over of one of the normal "voice over guys from the 80's" and a starfield. All the others escape me.
