This is a show that compels you to appreciate the art style and quality, similar to Bakemonogatari. The story highly tests your tolerance. If you give up, it's over and you miss the positive byproducts which comes afterwards. Everything about the sound especially the soundtracks are kind of weird but it just works every time.
At first glance, you might think that this show is just a rip-off of Dragonball Z with katanas ( like literally ) and good art and quality. However, Katanagatari gets better as it progresses so if you think that you have enough patience then this anime might just be for you. Provided that you don't mind OP Mc, OP supporting characters ( a few ) and a story that doesn't really have a good nor bad ending as it simply tells a tale of a man who lived.
I guess I could say that this is pretty much the bakemonogatari version of Kill la Kill. Was very difficult to binge but it was worth it.
