Initially Nightmare Teacher (or Nightmare High) seems like your typical highschool drama but after the first episode it becomes clear that the story is far more deep and innovative. The plot focuses on personal desires of young people whether it may be popularity, appearance, intelligence etc and the consequences of not being content.
Teachers are meant to lead us along the right path through learning, in some circumstances the only way for one to learn is through experience and consequence and Nightmare High explores this concept in a fantastic meaningful way.
There is a light element of horror mixed in with some mystery. By the end of the series you are sure to have more questions instead of answers, particularly about the antihero. The ending of the series is left largely open to interpretation where the viewer will try to piece together everything and come up with their own unique conclusions. It also stuck with me for a few days!
I thoroughly enjoyed Nightmare High and I hope a second season is being considered. Perhaps with a lot more focus on the mysterious antihero. On the side note, the soundtrack for this series is beautifully composed.
