There was no need to change the Klingon look. They had developed them so well and this just looks like garbage, just like JJ's Klingons. If this is them slowly getting that virus that changes them into more human looking Klingons, then that's fine, but if this is just their new look, that's just stupid. You can evolve the look of the Klingons, but to destroy the look of them from what they had so awesomely developed to this lame look just stupid. Not only that, but they all look pretty much the same.
I'm still wondering if Number One is the daughter of Trip and Topal (spelling?).
