Didn't watch the show or the pilot because empathizing with literal demons doesn't quite sit right with me and I'm not even religious. Would it be better if it wasn't set in the literal Hell but somewhere more abstract and still had more or less the same characters and premise?
I have a passing interest in the occult, so bear with me as I ramble for a second. (And rev up those puzzle piece reacts.)
Something worth noticing about
le current year is that there is a trend for (most notably LGBTQ+) people to embrace demonic/Satanic imagery. In my experience, it's an act of rebellion toward that individual's religious upbringing or traditional culture. The problem is, one would think that the best way to rebel against religion/tradition, is to simply embrace nothing. However, embracing nothing doesn't make you many friends. So bearing some kind of iconography is just a substitute for religion as it is another way for people to identify one another (you know, like the ice-cream flags or Redditor Atheist t-shirts).
The thing that bothers me about this is whether or not you're religious, there's an implication these people often miss. That is:
1) If demons are real, they expect an equivalent exchange for their service to you, which - without proper education and precautions taken - can lead to one's destruction. (see: Aleister Crowley)
2) If demons aren't real, simply using demonic symbolism is a giveaway that you are a self-serving individual with no interest in the world outside of what it can do for you personally.
Setting Hazbin Hotel in a place other than Hell would have made the project forgettable. Hazbin and Helluva are for people who are currently in (or stuck in) a rebellious phase who think there are no repercussions to being "a sinner." However, like I said in a previous post, the "sins" committed by the show's characters are a child's Disneyfied view of the sinister side of humanity. I think everyone on the planet is willing to admit that the media you consume is going to influence your behavior. And while Hazbin Hotel has an adult rating, it is obviously made for teenagers.
All that said, I try to not wear my tinfoil hat too tight. I'm just an idiot on the Internet who likes cartoons and animation.
The most reasonable opinion is that having a show take place in Heaven and Hell sparks discussion between people from all walks of life. Even secular, educated people have read classical literature that features Heaven, Hell, Satan, and demons.
Any time you talk about X, Y, or Z media, you are giving them free advertisement. Also, demonic iconography is in the public domain, so even if you don't want to buy Hazbin or Helluva merch, you can still signal your love of a show by purchasing a Stolas sigil off of Etsy. "Seize unclaimed territory" is common advice given to people trying to make unique art. Public domain is just free real estate.
