Worth the half way forward.
Characters without much charisma, except Mizuki, she really carries the anime alone.
The animation up to half of the anime is common, more like a tv anime than a movie / short.
The design is the same as animation, bland and common up to half, after half becomes a bit more interesting, but nothing much.
The music is weak also, common compositions, however the sound mix is good. She who saved the anime in this question.
Dubbing is cool, really nothing more. There is not much that the dubbers work, we do not have many scenes that required a good performance.
Want an anime with an good ending, but nothing captivating? Go on that one.
