My only reason for disliking the new Klingon look is that it just felt like it was doing it for the sake of doing it rather than having a good reason to do it. If they wanted to take the TNG look and make it even more alien-looking due to advances in prosthetics it would have been one thing, but they pretty much threw out everything but the ridge heads.

Also, and I’m guessing this is because of what they had to wear in their mouths, the Klingon language got suuuuper slow. Especially with Voq. It made the scenes a lot longer than they needed to be. Voq’s speech in the first episode just dragged.

Most of the other visual changes didn’t bother me much, since they generally made sense and just were because effects had improved, but I just don’t know why they changed the Klingons other than because they could.
