Even when I didn't watch Hazbin Hotel ot Helluva Boss fully, i have some words to say regarding worldbuilding and design, i think...
The idea of multi-layered Hell may sound 'neat', but with writing plot holes and all, it wouldn't work when other souls going straight to Pride Ring and cutting off the opportunity to see other type of sinners besides Pride ones (if i did miss something...meh), so, why not just make Hell a flat disk (akin to Flat Earth or Discworld, or something similar concept of flatness) or - turn Seven Rings of Hell into Seven Sinful Moons that spin around Heaven (i could imagine this planet would've been outta clouds, floating plates with growing plants on it, and mash it up in solarpunk magitek aesthetic, besides whatever angelic tech they're using, cuz why not?)
We have only introduced to Biblical Hell's and Heaven's inhabitants (like succubus, hellhounds, imps, angels, cheerubs etc.), it's not hard to make some research (if you don't have enough energy or motivation) to add more than just Biblical Hell and Heaven, with precision take, so we could get more diverse Hell and Heaven (and not ending in worldbuilding dump situation. Also, why not expand eldritch beings a bit bigger here since we have vok Eldrich)
Why make Stolas as a baby and Paimon as a daddy to him, if you could've made them immortal ex-archangels that rebelled against heaven before they were banished (like in the book), so they could be related as 'cousins' by technically speaking (and imo, Emily and Charlie could've been a cousins too?
There are certain designs i may have liked (looks up at Sera's and Emily's grey skin as black, Alastor's twig like body and Bee's design. Coughs), but I won't deny that most designs are so bad, they could hurt your eyes, too hard to animate and just questioning, how do they even exist? Maybe I'll sound harsh or something, but Spindle Horse and Vivz had a chance to make a proper design (for instance give Hellhounds more diverse eye designs than just red sclera and red eyes - yellow and brown, bright pink, etc. Make some proper research of demons, angels and overall animals and clothing), but did she even listen? Nah! She thought she could do better designs than fan-arts (and certainly she made a slip here and crashed HARD by saying such arrogant and stupid words)
If HH and HB are happening in the same universe - at least there should be moments, scenes, even smallest details and hints to show some ongoing events in each show of the same universe (mayhaps I may have said tight or wrong, meh)
And I think that's all i had to say (tho it won't be last posts i may write down), tho you can point out or make a comment of what I've said or missed. And until next time, I'm out
I dislike how Helluva Boss and Hazbin Hotel are in the same universe. I even forgot that too. Like how Flaze said in his video how will it affect each universe.
