I won't spoil you too much with my review.

I would say that the series is worth watching. The actors did a good job. There is a new main character in every episode & every episode has its own story.

I like how in episode 1 the main character is done with his classmates bossing him around and at the end he gets his revenge. I knew that he had some plan because you could really see when you looked at him that his personality is changing... or maybe this is not the correct word, maybe I should rather say that you could really see that he is reaching his breaking point and it's only a matter of time when he will explode.
However I have a little criticism about this episode. I think ghost effect looks a little bit laughable and not scary at all.

In episode 2 I only wish I'd see some real tears from the actress, since it looks like she is regretting what she did out of jealousy, but I can just hear sounds of crying... and tears are nowhere to be seen. Also be prepared if you are like me and you hate seeing feet. You will be seeing feet a lot :(

I think people can relate to episode 3. Every day we hear what's beautiful and what's not beautiful. And I'm pretty sure everyone wished to be more beautiful than they are (in real life even the ones that are pretty by society standards still wish for something that they can't have). This episode reminded me of people obsessing over idols looks. And also "throwing away" their favorite idols when their looks change (either plastic surgery, weight or just their style) one day they were everything to their obsessed fans, the next day they're nothing when more beautiful person comes along. It was interesting episode and it was interesting to see how far these girls will go to become more beautiful.

4th episode also had some realism in it. You try to help others and tell what happened but then you also get in trouble with bullies. I would say that the ghosts and demons looked really great in this episode, and this makes me wonder why the ghost effect was that bad in the first episode. But I hated the wigs because they looked very fake.

In 5th episode I didn't like "the headless teacher" at the very beginning. The teacher acts more like you would act in a comedy... In previous episodes there were a lot of shady characters, you just knew that there was something wrong with them and they were suspicious to you, which was amazing. So this totally ruined the vibe of the series to me. Such acting just didn't fit into this series. I know the actor had such directions... and I would like such acting if this was comedy but it wasn't. I watched the start on 1.5x speed because I just couldn't watch this any longer. I was only at 11 minute mark and I was already so done with this episode. Comedic acting from everyone... yet this is not a comedy. And it didn't get any better. It was bad till the end. I hated every single second of it. And even when I was watching on 1.5x speed it seemed so long... it's like I watched 3 episodes instead of one.

I was really glad when 6th episode was finally normal again. I expected the old lady to have the missing body part of her son in that white cloth (when the cook mentioned missing body part I knew right away that whatever was wrapped in that cloth. So yes it was a bit predictable but still a great episode.) I did not expect that the school boy will actually kill an animal so he could prove his point. Great acting from everyone, I loved the old cooking lady.

Even though there was already theme about bullying in the series 7th episode was still great. There is nothing much to say other than the acting was good. The boy went from scared to pretty much "insane" when he realized that his wish came true.

8th episode was the best out of all of them. Even though all of them (except the 5th episode) were great, the last one was truly amazing. It was very touching at the end and yes I got tears in my eyes. It was a masterpiece.

The scariest things in this series are not ghosts, blood, death, suicide but what people do when they reach their breaking point when people bully them every day. Doing things out of jealousy as soon as they hear something and they don't even try to confirm if what someone told them is even true or not. Obsessing over other people and forgetting your worth.

Was I scared watching the series? No. But I have been watching horror movies since I was a kid. But it's worth watching. Even if you're not freaked out by ghosts, blood etc.

I think I could totally re-watch this series when a lot of time passes and I have nothing better to watch. But I would never watch episode 5 again.
