Judging by the poster, I expected horror. Checking the genres, I expected a suspense thriller. At the end - I did not get any of these. It's a well crafted and written psychological drama that uses the supernatural elements to tell the stories of two young girls, and how they confront their past and the mistakes that they made.

Detention serves as a commentary on youth's problems and how they and adults perceive and deal with them. We follow two different stories, set in different time periods, yet resembling each other a lot. Liu Yun Xiang and Fang Rui Xin try to work around the restrictive and outdated school system and the twisted mentality of the adults running it. Both girls had to face family and relationship problems that led them to take, at times really drastic measures.

I loved some characters (the list was really short though), and hated many. Not everyone got what they deserve. There are some triggering themes included in the show, so I would advise checking the tags before watching it. That said, they were presented in a quite realistic manner, showing them as something serious and not easy to deal with.

The production value seemed high. The show is shot in an interesting and aesthetically pleasing way. Some camera work choices perfectly complemented the writing and the plot points happening on the screen. I honestly do not remember any song or instrumental used in the series, but I am confident they were all fitting (would most likely remember if they weren't - one always remembers what they dislike).

The acting was believable and the delivery was ranging from good to great. I only had a problem with Wen Liang's dad. The acting was just quite robotic and not on par with the rest of the cast.

Overall, if someone looks for a horror or a thriller with fast paced plot and a lot of suspense - this ain't that. If someone wants to see an emotionally driven story with romantic elements, that comments on overwhelming pressure that is put on the female leads, family drama and struggling in a constricting environment, with some nicely done horror/supernatural elements (mostly in first and last episodes), then this is for you.
