A lot of people think this show is dark and that it's not for kids, but I think it's all based on what you've watched in the past. If you're like me and have read both A Series of Unfortunate Events and Harry Potter when you were 8, then this show is not too dark. But if you've spent you're whole life watching Sailor Moon, you are too pure for this show and should not watch it. This show goes over some heavy topics, but I think I would recommend it for 10-year-olds and up. The show is about as dark as A Series of Unfortunate Events and Harry Potter and is as violent as Star Wars. It is a really good show, and while I think 10-year-olds can handle it, I'd more or less recommend the show for middle school girls since you'd relate more to the characters. I am 12 and really like this show, so take what I'm saying with a grain of salt. Very good show, though.
