IIRC my main issue with the show, in the first few eps I watched, was the preposterous idea that the very concept of "vision" was taboo. Like, what did these folks think eyes were good for when they could experiment with their horses and dogs to realize that when it is hot (I.e. sun is up) these animals, also with jlelly filled balls in their head, could suddenly navigate very well and react to things far away. Or if you covered said jelly filled balls the horse suddenly didn't move well.
Anyway, the conceit of the show didn't seem matched to the narrative thrust of it, the internal consistency wasn't there for me.
