Hazbin Hotel Is GREAT ... Except When It Isn't

Hazbin Hotel, the cartoon originally created by Vivziepop, distributed by Amazon, has gotten wide attention throughout the animation community. With both vicious criticism and mass appeal, I touch upon the areas it could have improved with its musicals and writing, while praising its animation and overall energy.
