I'm really impressed about the extend they went for this little spin-off. They totally didn't have to and they did it anyways, it's not the best written story in existance, but it actually stands a fair chance.

Because they didn't go for just a spin-off, they wanted it to be a story that happened in-canon, and it actually works fairly well, sadly they really lazed out with P3D and P5D later.

The selection of music is great too.

Kanami is a lovely character, I really love her.
