Most of my exposure with anime was whatever was on Toonami and Adult Swim in the 2000s. I've not watched stuff like, Ghost In The Shell, Cowboy Bebop (only disjointed episodes out of order), Neon Genesis Evangelion, which I know are highly regarded.
I've seen just about every Miyazaki movie at this point. I've seen Akeria.
I'm sure there's more mainstream shows and non mainstream shows that I'm missing and would enjoy.
Thoughts?
MegaloBox is an under rated personal favorite of mine. It is a bit overlooked but it is supposed to be a spiritual successor to ashita no Joe. Only it kidna has cowboy bebop type vibes. There is a seccond season. They both have strong leftist themes which is kinda out of nowhere for the modern anime industry.
