This is going to be a short and sweet tidbit since I am fresh off finishing the show.

After having a nice buildup of plot, characters, and suspense, I for sure thought we were going to get a terrible cliffhanger ending that would never get a second season. Plus, as someone who hasn't (and doesn't really plan to) read the webtoon - it would be a very anti-climatic and disappointing end to the 8 episodes.
BUT.
All I'm saying in this review is that we got a conclusion, we. got. a. conclusion. A good one, a satisfactory one, and one that does leave room for expanding. (If they so please to do).

I loved the action, the blood, and the personalities of the characters. Especially the fact that everyone was really consistent in the way they acted, not that they don't have character development, but that their actions stayed in line and made sense as t what their character was built up to be.

Do give it a watch, if you like this kind of genre - happy watching people :)
