It took me a while to finish Long Khong because the first 2 episodes were like...Hmmm, I had to think about it. I'm glad I continued :)
Well, this show got me completely addicted; But I have a few points to note:

First, the acting lacked A LOT on some ways; It seemed as if the actors simply weren't trying hard enough, even though the effort seems to be made in some scenes; The CGI, monsters, and few jumpscares that happened weren't that great. It didn't merge well with the real life scenes, let's say that. At first I thought the amount of gore was unecessary, but as the show kept going, it started making sense and getting creative with it.
The good points of this series is, the plot is amazing. Oh, and the acting of the protagonist is awesome too, I'm so proud of her even not knowing who she is lol. I think is the first time in which I couldn't guess the plot twist, even if I tried hard, and it hit me so bad. It's addicting and at least to me, it is worth it. You can expect emotional rollercoasters with it;

I would rewatch it.
