Tons of new anime are released every year, but the world of modern anime is vastly different from the classic anime series that pioneered the genre—and that's not necessarily a bad thing.
Animation techniques have improved over the decades. We have better art, stronger characters, more imaginative worlds, and we're moving away from overused anime tropes of the past.
But newer isn't always better! There are plenty of old-school animes that are just as good today as they were when they first debuted, even if they feel dated in some ways.
Here are our picks for the best classic old-school anime series that may be old but are still gold. Even if you're an avid anime fan, you may have missed some of these!
