Took some inspiration from Percy Jackson and made it about mythological monsters in America, then had teenagers sort it all out. All be it older and more experienced teenagers. Take Erin for instance; he is the actual Fairy Doctor not because he was born into a long family line of Fairy Doctors (he was), but he is knowledgeable because he spent his entire life being taught everything he needs to know about how to combat magical creatures. No montage or hero sword for him.
