Sorry, I realized later you were looking for an actual anime show rather than a music video.
Art style preferences are a personal thing for sure. I like the contrast of simplistic character designs against the imposing industrial, post-apocalyptic cityscapes that they travel through. More often than not the backgrounds, machinery, etc. are drawn with greater detail than the girls themselves. I also like how they could be philosophically discussing what it means to be alive, then suddenly encounter some half-Godzilla sized robot that nearly kills them by carelessly dropping huge beams and bolts all over the place. I’m watching it for no extra charge on Amazon Prime. Other anime I am currently enjoying on Amazon Prime are Vinland Saga, Made In Abyss, and Wotakoi.
The annual membership for Prime is about the same as a year’s worth of subscribing to a competitor like Netflix or Hulu. Yahoo! was streaming anime for free until last year. Funimation also streams anime - looks like a similar deal to Crunchyroll in which you can stream some shows for free, but have to put up with loads of adverts, which go away if you pay for a subscription.
