The anime has a lot of references to old school anime as well as some to things that has happened in Japan. This makes this anime, without a doubt, a Japan targeted one, but even without getting the references you can have a lot of fun watching it. I didn't particularly like it, but it made me laugh and I had moments of going "What?" laughing either harder.
Most of the characters are over-the-top, which also makes this anime more enjoyable. The 12 episodes were just about the length this series needed as it's not necessarily the anime you'd show to kids and has no actual plot. Perhaps unless you live in Japan. Harumi - a human, unlike the Demon Patrol consisting of Enma, Princess Yukiko, Kappaeru and the hat Chapeauji - gives a lot to the show even though she's quite plain.
I would have to say this anime should be watched with an open mind, as even though the animation is better than it generally was in the 70s, this show is as much 70s as it could be.
I'm friendly enough to give a rating to this one, and as I was enjoying it but in overall didn't like it (this sounds odd, but there are shows like that, at times), it gets the hard-to-get 3.5 rating.
