This anime is the kind of anime you have to go through so that you enjoy it.
Firstly let's talk about the art. It's okay. Its 3D is better than Aikatsu's at its beginning, Kirari's, Sailor Moon Crystal's transformation's and so on. The 2D is not that great, but it is fair.
The music is great! The OST is kind of boring, but the songs and the openings (especially the second) are interesting!
The characters seem really show at the beginning of the anime. But as you discover them, you see that they're deep. Not especially original or complex, but they are definitely not clichés.
The story is harder to criticise. Precisely, the beginning is just awful. It is probably the worst beginning I've watched, seens, listened or read. You just can't understand what's going on.
But the story gets better, and the end is far from being good. It's brillant. I won't explain why, but the end of the anime is just excellent.
And somehow, I loved Prism shows. I don't know why. They aren't that great. But the anime makes you understand that they are more than show, that it is a reflect of your soul. It may not affect you at all. But, for my part, I've just felt amazed and affected. I know it is not that good. But somehow, I love it.
This is why my overall grade is 7/10. I guess that it truly deserves 5/10. But I can't give that. Because it truly resonates with my soul.
