As someone who’s been watching anime since the days of Star Blazers and Robotech on syndicated TV, I’ve seen trends, cycles, and genres rise and fall.

Streaming anime has made it easier than ever to access these buried treasures.

Here are ten standout series (some old, some modern) that I think every serious anime fan should check out.
