Akira is the anti-thesis to Disney in any way you can think of.
In other words: you can take almost anything except animation and the negative version is Akira. Where Disney is easy to understand, Akira is hard to understand. Where Disney is fluffy, Akira is hard as a brick. Where Disney animates people as if they are bad over-acting actors, Akira is about realistic animation. Where Disney is “for children”, Akira is for adults etc etc pp ad nauseam, I think you get the picture.
I really can understand that Akira, at the time of its release in 1988, blew the mind of western audiences.
Basically this is also the reason you have to watch Akira, even if you don’t like anime or animation. Even with all its flaws Akira is not called a landmark animation, even a classic, for no reason.
