There's quite some similarity between the Klingons of Into Darkness with those in the Discovery trailer.
Could they possibly be as the result of further genetic alteration or surgical alteration to counter the effects of the loss of their forehead ridges as seen in season 4 of Enterprise?
OK. That may be an explanation.
Well, an explanation of some of it. Not of what the ridiculous things they are wearing :P I guess there might be some sensible eplanation for it all (further genetic modifications, members of a cult of some kind etc) but again, it all comes back to this needlessly being a prequel. If this was set 50 years after Nemesis instead of being annoyed by things like that I'd be intrigued, accepting of everything that looks new and different, because that's exactly what it should be then. With a prequel, and one set so close to the known events, they don't have much freedom without messing stuff up. Why didn't they just set this post-Nemisis or in the Kelvin timeline I'll probably never understand.

BTW: I find it hilarious how hard they tried to avoid white males in this "Discovery" thing.
So yeah, no need to bring this most annoying of pointless internet wars into this. Please. I know that argle bargle SJW monsters argle bargle nazis, but I'm sure there's a 4chan thread for that.
