This review is going to be from a person who work in films. The crew in the series worked really hard and that is shown, however it lacks perfection in all the aspects, and some of the technical stuff really bothers. Story wise it has a great concept, but very often it has scenes that don’t make any sense to the story. [SPOILER] One example is how Lilith is known in the monastery as the best fighter while Mary, another nun, says at the beginning she doesn’t know how to fight because she had guns. However, a few episodes later, Lilith suddenly is beaten badly three times in a roll by Mary without any struggle and that’s only one of the many examples throughout the storyline. If these little things don’t bother you than it is very entertaining, but for the more picky like me it can be a real stress
