Absolutely beautiful animation, a detailed but easy to understand plot that you could rewatch hundreds of times and still catch new things, complex characters with meaningfull motivations that are difficult not to relate too. You don't need to understand league of legends lore to understand Arcane, infact I'd especially recommend it to people who haven't played. Arcane is truely an amazing work of art that leaves an impact on the viewer, and a show that I believe everyone should experience.
(Also I'm 100% rooting for Cait and Vi to happen)
