I don't know. I suppose Monty is trying to make the show kid-friendly, but it can be pretty violent at times. I wouldn't show it to anyone under the age of at least 12.

And, to be honest, I'm glad that there's mature elements in RWBY. It's impossible to tell a decent story that's completely kid-friendly, or aimed at kids. It's too restrictive.
