Two specific points struck me as I was watching the first three episodes of Arcane.
The first was the series’ use of a “camera.” Animation, by nature, unchains the camera view or perspective from having to be anything grounded by reality. Arcane deliberately chose to use shots that could only be achieved by an actual camera following the characters (to a point where, in the first episode, mud spatter appears on the camera “lens” and obstructs the shot as characters are sliding down a dirty metal tube.)
The second was the use of art nouveau trappings specifically for Zaun and art deco trappings for the architecture and design of Piltover. These appear to be very deliberate choices due to how consistent they are and also, the few times that these unspoken design “rules” are broken.
Full disclosure, I am contracted by Riot Games for their League Championship Series esports broadcast as an analyst. I had no idea as to what Arcane would be about, saw no preview material that wasn’t publicly available to all, and was not told to write this; however, in the interest of disclosing any and all biases, I felt this necessary information.
Also, there will be spoilers for Arcane‘s first act.
