Megazone 23 is a relatively obscure cyberpunk anime that has huge prominence in the oldschool community. I'd strongly recommend this anime because it explores hyperreality and I'd argue its better than the Matrix series. It has all the 80s cyberpunk codes of conventions you could ask for. The enigma is brilliant and well paced. Plus, the soundtrack is lethal. One criticism I have about this movie is that I think the character designs didn't age well.
