There's some stuff in here that I would definitely not call a masterpiece (To Aru, Nagi no Asukara, BRS, any Key property). The thing is, there are very rarely works that achieve a grandiose artistic height and a level of importance to be called a master work. Some examples that I would definitely use, even if I don't like some of them, would be:
- Akira
- Revolutionary Girl Utena
- Millennium Actress
- Evangelion
- Ghost in the Shell
- Cowboy Bebop
- Angel's Egg
- Wolf's Rain
- Madoka Magica
- The Tatami Galaxy
- Penguindrum
- Grave of the Fireflies
- RahXephon
- Serial Experiments Lain
- Princess Mononoke
- Porco Rosso
- Beck/Paradise Kiss (very similar shows, basically with the genders switched)
- Welcome to the NHK
- Flag
