It looks super interesting. That there's gore and a horror behind a story that apparently doesn't have much to offer catches my attention. It's the same for me with the blessed Ecchi scenes, I don't understand why they include them if they don't add anything, they bore me when there's no context for them.
Anyway, it looks good, the animation certainly looks top notch and a story of suspense and terror is always good.
the movie was entertaining, its animation is very good and makes it fun, although it is not the best in terms of horror or gore it is good. but as you say Ecchi in forced moments or in stories that are not based on that as the main thing just looks a little bad.
