Jojo's Bizarre Adventure is very accurately named

So I've started reading Jojo's Bizarre Adventure, and found it to be perhaps the 80s-est manga ever. The book is just wall-to-wall huge guys overemoting and blowing up heads, and I'm only midway through the second volume. That page to the right actually summarizes the story so far remarkably well - crazy mask powers, daddy issues, yelling, and straight up jamming fingers into a dude's brain. Dio Brando, a pantomime villain of the always-easy-to-write "born evil" variety, has activated an ancient blood-fueled Aztec mask that jams tentacles into his brain, killing him and turning him into a vampire in one smooth motion. Our hero, JoJo (for "Jonathan Joestar" a reasonably normal name for a book with a character named Speed Wagon), archaeologist, football star and 1st Edition paladin, who has been living with Dio's cartoonish villainy for seven years now (literally, DadJo adopted him) but unable to bring himself to save the world a lot of grief by just killing the asshole, is feverishly trying to work this out while Dio runs around draining cop's life essences by fingering their frontal lobes. Whatta feeb; Dio's a raging, dad-poisoning, dog-killing hardon, but at least he gets shit done.

Are there valuable, gameable ideas to be gleaned from all this nonsense? Perhaps. If not, hey. an awful lot of guys are going to get their heads karate-chopped in half, and that's always an entertainment bargain.
