i guess that depends on how pedantic we want to be.
the last unicorn was animated by a japanese company, but written and directed by us americans. original voice performance was also done by non japanese people.
so if we say that a anime has to be a animated movie made by japanese people, then no, the last unicorn is not a anime.
if we say a anime is a animated movie where japanese people were responsible for the animation then yes, the last unicorn is a anime.
if we say anime is a genre descriptor and not a geographical label i wonder if avatar the last airbender or the castlevania animated series are anime and how ghost in the shell and my neighbor totoro both fit in their.
not a native speaker, so what does "sparkling" entail here?
i only know the word when talking about fizzy water, jewelery or twillight vampires :D
and would you say tlu is anime?
it was animated by japanese people in japan after all.
