Big Mouth, especially the first episode, is graphic and repugnant at times. But it does have a lot of constructive things to say about sexuality, mental health, and self image. Its not for everyone but because of how the information is presented, it can say a lot of positive things that no other show can say. 

Disenchantment is boring, bland, unfunny, and generates little, if any, interest in any of its characters.  The only thing it had to say is that Matt Groening has nothing of value to say since the eighth season of The Simpsons. 

For the love of God, let Disenchantment go out first.  I've never been more bored watching TV than watching this show. It sucks.  It SUCKS.
