Classic or modern anime — the debate for which one's better has been going on for a long time. However, most of these debates end with classic anime getting the thumbs up. Why? What makes classic anime so entertaining even after decades? Even though old-school animation is nothing compared to the visual treats of modern anime, there's something that makes fans want to go back to the classics. Although it's difficult to pinpoint precisely the timeline that turns an anime into a classic, it's safe to say that it's anything before 2010. And the more time passes, anime released after 2010 may also become classics.
