I am barely half way through the drama, but I am loving what I have seen so far. Usually I stay away from anything horror related or republican era dramas. However, this drama is an exception as the episodes I've seen so far didn't scare the crap out of me nor is it as depressing as most republican era dramas. There are certain parts that gave me a bit of a scare, but nothing too bad. However, if you do scare easily, it would be best to watch in morning or afternoon.

Also, I find the psychological part of entering into an individuals subconscious to find answers a very interesting and unique part of the story plot. Yes, it's a bit far fetched from reality, but this is a drama so anything can happen and it is pretty cool. I am also really enjoying the team of three working together to solve the cases, while trying to uncover the really identity of the mystery force that is popping up everywhere.

I may be biased in my ranking, but I do believe that this drama is way better than the 7.5 rating. If you are an individual that likes or can handle the lost tomb series or the candle in the tomb series, then I would recommend you to give this drama a try and see if you like it or not.
