Even though I love both series, they have a point. I never understood why so many people hated SAO. It was such a good show, just faster paced, which is honestly better than a story line that moves too slow.
A good example of being torn between good and evil. Death Note is a show where the main character is an anti-hero. He finds a notebook that kills the person whose name is written into the book. The main character, ironically named Light, finds the book and kills all known criminals on Earth. Murder is illegal but he's also doing a civic good. Is Light evil or good?
