This list ranks all of the anime that I have given a perfect 10/10 score.
1) DOES NOT INCLUDE animes that I mainly view in manga form, such as Naruto, One Piece, Bleach, Negima, etc. I might consider the anime versions of some of these mangas as better than some of the animes on my list, but regardless, I will still not list them here.
2) Animes listed here include all seasons of the series, even if different seasons of the same series go by another name. Thus, for example, Code Geass: Lelouch of the Rebellion on this list also includes the second season entitled Code Geass: Lelouch of the Rebellion R2. Spin-offs are considered as separate entries.
