This Collider list highlights ten anime series the author considers "near-perfect" yet largely forgotten today, overshadowed by modern hits such as Frieren: Beyond Journey's End and Demon Slayer. The selection is based on factors including past popularity, current lack of relevance, animation quality, writing, originality, critical acclaim and fan opinion, acknowledging that while these shows retain cult followings, they have faded from mainstream memory compared with their earlier prominence.

Featured entries include Nichijou, a comedic slice-of-life series about the everyday absurdities of high schoolers, a young professor and her robot housekeeper; Magi: The Labyrinth of Magic, an action-fantasy about dungeon-conquering "king candidates" that lost visibility after over a decade without a new season; Space Dandy, a genre-blending sci-fi comedy from Cowboy Bebop director Shinichiro Watanabe; and Megalo Box, a modern boxing drama praised for its underdog first season and darker, addiction-focused sequel. The article notes most picks date from the late 2000s to mid-2010s, though it argues even recent shows like Megalo Box can already be overlooked.
