The series explores the life of a 19-year-old woman who wakes up in a morgue and has a divine archeological tool included in her back as she tries to understand what's going on. Over time, it seems that this girl is discovering that she is now part of an ancient system that has been charged with fighting demons on the ground, as she tries to undergo a unique experience.
The silliness never really goes away, and the show knows when to really embrace it, but that's fine - Warrior Nun succeeds by telling a story of demons, literal and figurative, that always puts its human characters first.
Warrior Nun is a truly wild journey that manages to ask some tough questions while equally embracing its silliness, its action, and the absolute absurdity of it all. The show may not be everyone's cup of tea, but it is one hell of a fun ride.
Basically, Warrior Nun is too nutty not to have a season 2. It is, after all, quite entertaining, if one doesn't mind the portrayal of the Catholic Church, or any faith, as a sanctuary for unearthly conspiracies and divine mischief.
The script can sometimes lean too much on mythological and religious exposition... but the actors have such good chemistry that their various pairings work, and the smartly choreographed fight scenes are well-placed.
