Anime is plain art (sometimes)
From Wiki to spare my typinghands..
Art refers to a diverse range of
human activities, creations, and expressions that are appealing or attractive to the
senses or have some significance to the
mind of an individual. The word "art" may be used to cover all or any of
the arts, including
music,
literature and other forms. It is most often used to refer specifically to the
visual arts, including media such as
painting,
sculpture, and
printmaking. However it can also be applied to forms of art that stimulate the other senses, such as
music, an
auditory art.
Aesthetics is the branch of philosophy which considers art.

But time is an important factor in this, over time art can change in peoples eyes to "this is not art" and later on can it rise back in the "yes this is art" section again.
In that view is antique much simpler to describe.
