Not the best of its category, but it got my interest and kept it till the end. It's kind of predictable, and the director always has to show not just clues but who really is behind the "bad/weird thing" that happens, which is very annoying, because it's underestimating their audience. They didn't need to show us that thing on the back of the girl 15times, we got the point from the first time. Acting isn't the best, but it's tolerable. It's definitely worth my time. I recommend it to people who like these kind of stories and series. Just don't expect this to be the best.
Edit after the middle of 2nd season: It's getting more lame and cringey. Every clue they need is miraculously exactly where they need it to be. The so-called jokes have already become unbearable.... Everything is becoming dull, acting is even worse, watching it is just painful at times. I'm really trying to keep till the end, but it's getting harder...and also more difficult.
