The premise of the show is really unique and original. I just binged everything in a day. And I love it. I love the whole show. At times it can be hard to think of them as being blind but some of which they do, like the marking on the open palms, the knots on the string, the wind chimes etc and using their weapons as walking sticks makes it really believable.
What is annoying though is the people complaining how unbelievable it is. Blind people today are able to survive. Its not like their totally helpless. They have ways of counting the number of steps they take from place to place. A walking stick, etc
Keep in mind when you watch this...human beings have lost the ability to See over a couple hundred of years. All the complaints, are like everyone lost their sight in a generation or 2.
Like no...its like 300 or 400 years. They adapted and they memorized. As well as they have the other 4 senses...
So often time they are feeling, sensing and hearing the tiniest sound. Which over the hundreds of years of the ability to hear as well as the other senses go stronger...they pass it on
Anywho...watch it. You will love it, if your looking for something original with amazing cinematography, great characters...and have exhausted all your netflix options from being on lockdown
