"A mistake" is a strong word maybe because I'm sure there are still good anime, just that it's dumb that the characters all have similar animation styles for their eyes and bodies. Like animation in other countries or not at least they have different designs of people from each other

Yeah I've watched some Cowboy Bebop. It was good but in anime sometimes eye designs even when somewhat different are much more similar than in other types of animation
