While the first two episodes started strong, the series got weaker going on.
Mixing a criminal plot with supernatural beings is a fine line to walk and they tried too much without much of a thread to connect it all.
The production value was high, but the acting left something to be desired.
Overall this show is not as good as the ratings make you believe, but not as bad as many others. The CGI was at least medicore.

The worst was the finale with it's cash-grab for a live streaming event which I find very disappointing. Why do they need such an event, did they just want to milk the fan base? The ticket price was astronomical for Thais.

The story that didn't follow a strict plan and got convoluted later on, so the show could not live up to its potental. If the supernatural parts would not in it, they could have saved a lot of money, shorten it to eight episodes and the result could have been better. Also when the supernatural character is female, why has the male actor take that part too? That was a really silly decision. It's always bad when a show starts so strong and falls off a cliff later. I was really disappointed.
