Web magazine Cyzo interviewed anime director Hosoda Mamoru. At the end of the interview, Hosoda expressed his objection to the recent trend of releasing anime movies derived from TV series.
I think producing a movie by means of animation has a broad potential. However, Studio Ghibli, or rather, Miyazaki Hayao has been the only successful anime movie producer who exerts himself (for creating the original works). It’s sad to see the rest of the producers missing the chance to create a wide variety of anime movies. …
Recently some robot anime movies are produced based on TV series. But they are merely running character business through the movie media. I don’t criticize robot anime itself, but at least they should have produced original movies. TV-derived anime movies don’t expand the creativity of the industry nor fulfill the social task of animation movies.
