Yes, in my opinion, Season 2 is worse than Season 1. I wouldn't say it's significantly worse, as I only really disliked the finale, but it's definitely weaker. I take comfort in the fact that we already have previews for Seasons 3 and 4... I mean, Vivienne spoke about the future of Hazbin Hotel. Season 3 will be in two years and will likely focus on family themes.

Good review, best regards :).
