Maybe this is unfair, because it's partially based on my own lack of expectations and understanding going in, but Gannibal's first season was a pretty serious small town supernatural thriller whilst the second season is completely unhinged and immediately loses any suspension of disbelief.
It is based on a manga, which is probably why it increasingly feels like it was wrriten for edgelord teenagers and young men by an incel, but the way the tone shifts so quickly between the two seasons makes it feel like two entirely different shows. The new characters introduced in season two are such stereotypical shonen/seinen manga/anime cardboard cutout characters with absolutely no depth or realism to their scenes or performances.
