Seems like an original premise, ey?
What I really like about this series, is its crazy humor, which is this author's famous trademark.
Comical explosions galore, funny wtf momments, and generally American cartoon violence, in general.
Another thing that I like is that for once the bad guys are the exorcists! Usually the demons are the bad guys, not the heroes.
If you want a great supernatural comedy WITH plot. Check out Kanpai!
