The original shaman king was a huge part of my childhood, even before I was aware of anime. I used to watch it in primary school with my classmates. Overall, Shaman King 2021 is a gift from the Great Spirit. Pompadours off to Hiroyuki Takei and Studio Bridge!
I actually like Shaman King 2021 Netflix version a lot. It has a faster pacing, but in a good way. It has a more modern, fresh shonen vibe to it. The characters also have stronger personalities and their reasons to fight are highlighted more than in the original.
