Big Wars: Kami Utsu Akaki Kouya ni

Before the likes of Saint Seiya, Dragon Ball Z and Pokemon conquering the kids in the west, it was actually Akira that opened the door and made people realize that the cartoons coming from Japan weren't what you would expect from Disney or your TV channels.
A huge flood of VHS tapes came showing animations with mature themes, absurd plots, and enough graphic sex and violence to make parents freak out... what a glorious time!
They don't make cartoons like this anymore.

This is a comprehensive list with stuff from very good to very trashy, but all in the same spirit.
Some early 00's also included.

ps: I also recommend, but can't include here, the second Violence Jack movie, A Kite and Mezzo Forte.

Grumpy Jii-san was an anime reviewer and hiking enthusiast. Many of us were fond of him. This is the fifth and final part of a list of the anime he reviewed in video order from oldest to newest. They are presented without his score as mild encouragement for you to watch his reviews.
