YMMV / Cool Shock B.T.

• Harsher in Hindsight: B.T.'s criminal, anti-social behavior is hard to enjoy even if he is a Noble Demon who sincerely cares for Koichi, given that Dio Brando, an expy of him, would viciously deconstruct each and every last aspect of B.T.'s character and become easily one of the most evil characters that Hirohiko Araki has ever written.
• Hilarious in Hindsight:
  • Manabu winds up getting hit by an ambulance that was meant to pick up his family, which is hilarious after the events of JoJo's Bizarre Adventure: Diamond is Unbreakable, given that its main antagonist, Yoshikage Kira, winds up getting killed in the exact same manner.
    • Similarly, the story being framed as a series of narratives told by a small, unassuming everyboy named Koichi about his strange new friend is also quite funny in light of Diamond is Unbreakable, which uses the exact same framing device.
  • Manabu and B.T. make a bet for the former getting to have Koichi's dog if he wins, while Koichi keeps it if he loses by using ants and two pieces of candy, with Manabu secretly cheating by spraying pesticide ahead of time in the place that B.T. chose. Hirohiko Araki would use this exact scenario yet again in Stardust Crusaders, only this time, instead of ants, it's a cat, and instead of two pieces of candy, it's two pieces of meat, with the cheat being D'arby secretly owning the cat, leading to it snatching the piece of meat that he chose before the one that Polnareff chose.
  • At the time, B.T. was considered scandalous for his criminal behavior. His looks would end up inspiring the initial appearance of Dio Brando, whose crimes would become far more severe in scope.
• Retroactive Recognition: Much like Baoh, the series became much more famous and respected after Araki's runaway success with JoJo's Bizarre Adventure.
• Values Dissonance: Reading it nowadays, even putting aside its now famous author's legacy, the series reads as a regular Kid Detective story. But back when it was released it was universally despised, even by most of the staff of Shonen Jump where it was first published in 1983. The main character being an Anti-Hero with the Face of an Angel, Mind of a Demon clashed with the magazine's core values of friendship and selfless heroism, the stylized art style was considered subpar to boot, and the series was quickly (even by the magazine's infamous standards) cancelled after only 6 chapters. Needless to say that it has been Vindicated by History since, and the magazine itself has published a lot more twisted Anti-Hero mystery stories after that (most notably Yu-Gi-Oh!, Death Note, and Majin Tantei Nougami Neuro).
