I watched the series through, and it was almost all setup and no payoff. They have four main characters, and three more main characters in the bodies they've taken over. The host / reincarnation can't interact directly in every scene, so the time we spend getting to know the reincarnations feels wasted, because often they're in a crisis and the dialogue is just boilerplate action stuff, and when they're in a quiet moment it feels wasted because its the characters having a schizophrenic discussion, whining, or wondering what has happened and what will become of them. Which is too many layers to deal with for little payoff. The weekly episodes didn't help this.
