There are a few questionable moments in it, but it doesn't matter in the long run. Puella Magi Madoka Magica is a really good one to check out if 당신 like action and deep plots!
(If you're worried about it, there are a few swearing moments and there's a lot of fighting... I'm only putting this because 당신 wanted PG anime. But just ignore it and let it go over your head. You'll be glad 당신 gave it a try! :) )
