This show falls apart over it's premise: everyone is blind as in BLIND not nearsighted, not bad vision, blind.
Every episode you'll have stuff that doesn't make sense and blind people either wouldn't do or wouldn't be able to do, not even after 600 years or even say... "I looks abanoned"... "watch out"... These words would simply ceased to be used especially with so-called Witchfinders running around hunting down people who have sight.

The production is great, the acting is okay, the action is far in between dull parts and areas you will say "well... no, that... doesn't work". People who have sight don't see people they should have seen, blind people don't hear or smell large bears sneaking up on them (cuz you know stealthy bears are all the rage), kids learn language from books by... teaching themselves (sorry, the knotthing doesn't explain sounds VS letters).

I know blind people aren't helpless but the way the species is portrayed in this series is just too shallow to be believable. If they had fleshed out what it would be to have a blind society a bit more, changed the story a bit it would be a good show. Right now it's mediocre and without verisimilitude. If you can ignore that then good for you but then again everything is great if you have can ignore the bad parts of things.
