The arrival of the new millennium, a golden age of creativity perched comfortably within the animation medium. Fans, even today, look back fondly to the dynamic decade of the 2000s and wonder just how it led to the evolution of anime storytelling.

The 1990s laid the amazing groundwork with masterpieces like Cowboy Bebop and Neon Genesis Evangelion. But in the 2000s, studios took bigger swings, and all their work paid off because the product was an endless stream of shows that captured hearts, told refreshing stories, were diverse in genre, and became infinitely rewatchable.

Now, over twenty years later, anime series that debuted in the 2000s remain adored because of their quality storytelling, epic visuals, and beloved characters. They stood the test of time way before streaming monopolized our watching habits and grew even more popular. Of course, every anime fan has their honorable mention regarding “best of” discussions, but the series on this list represent the wonder and nostalgia of the 2000s.
