Magical Girl is a show that seems like it would be for a younger audience because of the age of the characters in the first two seasons. However, Magical Girl's themes and serious attitude make it a show for a much older audience. Magical Girl's first season touches on the very delicate fact of child abuse and a child's desire to appease her mother's wishes no matter how cruel the mother is to her; the show does hit delicate subject matters during the show time which can make it too violent and serious for younger viewers but it does teach valuable lessons. It shows in the first season what people want when they are scared or lonely, and it shows how to make yourself heard when no one will listen to you.
Magical Girl keeps up a steady stream of serious attitude with slight humor through some episodes to relieve the constant seriousness. It's constant theme is to never give up on yourself or your friends and to always make your opinion heard. Indeed, a very powerful show that has never recieved the attention that it deserves.
