Let me start by saying I don't care for psychological dramas, crime dramas, and I don't like watching things about mental illness. This story brings forth the question, is someone born to evil or do they learn it? So many reviews talk about how they binge-watched this show. I could only watch one episode a day because it stressed me out so much!

I thought the story was very original, even though this isn't a genre I normally watch, I could tell that I was watching something that you rarely see. It was very Lord of the Rings. Who can say what you would do when your life is on the line? Does your true self come out?

The acting was phenomenal by everyone. I've seen most of these actors in other projects, and their work here was top-notch. At times their behaviors were very frenetic, but only when called for. For the most part, their acting was very understated, a lot being displayed in just facial expressions.

The camera work/cinematography/location really gave a feeling of darkness and fear. Each character was fleshed out very well, and you got more of a feel for them and their behaviors as you progressed to the next episode.

Without giving anything away, I had to deduct for the total implausibility of a few things that happened, in an otherwise believable (though terrifying) situation.

The music was not your typical music - it ranged from hard rock to opera, and it all fit in very well.

Rewatch value is low, only because, once you know what's going on, it doesn't hold the same impact.

I can highly recommend this drama.
