When it comes to age rating of this show, it can be appropriate for all ages bc the ''scary'' part of this show is just blood. This show has lots of fighting scenes which doesn't bother me bc that's not the type of scenes I'm scared of or feel grossed out of. It just matters on how well you handle with gore and blood. If that's not scary to you you'll be fine watching this. It truly doesn't matter how old you are, it depends on what type of things you're scared of :) (I'm only an 11 yr old)
