It appears that my review is the highest age rating of the reviews here. What I'm here to warn you about is that it appears that while most of the reviews here will warn you about the dark turn the show takes, none of them really give you a grasp on just HOW dark it is. Know that Puella Magi Madoka Magica is NOT a show for children nor is it a show for the easily disturbed, shaken, or depressed. Only incredibly mature teenagers should apply, and even then, with caution, as it has the capability of being nothing short of soul-crushing. Without going into specifics and depending on the person, Madoka Magica borderlines on pure psychological horror, and often deals with themes like depression, death, dispair, humanity, evil, and does not hold back when it comes to showcasing said death, depression, dispair, decapitation, torture, and WORSE, all envoked upon children of 12-15 years of age. It intentionally leads one to believe it is innocent in nature, and then strips everything away, revealing the true nature of the show. Not only are it's characters all too relatable, but their deaths and the way they are handled remains all too realistic and downright horrifying at times. The show's true nature is that of enough psychological torment and dread to make even the most toughened crowds shake. This may seem like I am overselling this, but Madoka Magica (as well as it's sequel movie, "Puella Magi Madoka Magica: Rebillion") has a way of getting under your skin with hardcore psychological horror, adult fear, all-too relatable and likable characters (and their horrific demises, all of which are again, children), and themes and concepts FAR too mature in nature for younger teenagers, children, and ESPECIALLY the easily shaken or depressed. Save this one for when you are absolutely positive your child can take that amount of weight.
But, when they are, Puella Magi Madoka Magica is one of the smartest, beautiful, and downright brilliant shows I've ever seen. Ultimately, these things are what make the show so incredible, and it's defiance of genre tropes and great characters make for some very original and and emotional viewing. It's unflinchingly dark, for sure, but for those old enough, it's all the better for it.
