Even among literature novels, "original" isn't exactly an easy concept. "Hero finds lost object, learns it is the key to his success in defeating overlord x who is planning on conquering/destroying/enslaving the world; Hero is last hope and if he/she fails, the world ends." This is a very common plot through ALL shounen/fantasy genre. It's framed differently, but it's the same. So why is this getting flak? It's interesting, who cares?
