I watched the first three episodes and really tried to give it a chance. I'm a big Jason Mamoa fan (from the Stargate days) and love post-apocalypse stuff but this was hard to get through.
The acting ranged from okay to pretty good and was the only thing that kept me going. I know they had a blindness advocate to make sure their portrayals were accurate but due to bad writing, none of that even mattered.
The premise has a lot of issues. There is no way humanity would have survived a mass blindness when most people today can't even survive without electricity. Even if people who were already blind survived none of them would have the survival or medical skills necessary to survive and bring the next generation.
Even if we ignored that, there are a lot of on screen issues like their need for aesthetics like fashion and ornaments which wouldn't matter to actual blind people. Not once did I see anyone cup their ears for better hearing, even kids know that.It would be super easy to wear cups on your ears for better hearing so why wouldn't anyone? Because it looks bad on screen.
It comes down to lazy writing. The writers did not imagine what it's like being blind or what a culture of blind people means. They simply wrote a compelling story and shoehorned blindness aspects here and there. They might as well just have made a The 100 clone, wait they did.
Finally, for all the people saying this is such a unique idea, it is not. The movie Blindness was released in 2008 and was based on an internationally best selling book has pretty much the same premise but way more realistic. The movie also starred Danny Glover, Mark Ruffalo, and Julianne Moore, it was okay.
