Or maybe it does get better after season 1? Since everyone seems to love it.
I'd personally recommend giving season 2 a shot, if you still don't like it then the shows probably not for you.
As others have said though, it definitely gets better as the seasons roll on, along both the humor and drama fronts. The final season has many of the funniest and most poignant moments of the show.
I think bojack hit its stride over time, but I always liked the juxtaposition of dark reality with cartoon silliness. On some level I think it reflects a theme of everyone else’s life seeking to be so simple and stupid and trivial compared to your own. Of course even Todd’s problems are shown to be pretty real even if they’re also cartoonishly comical.
You know what I meant, hopefully? I predate the Simpsons, and I remember when they and their brand of humor first appeared. I also remember how annoyed I felt towards Family Guy (a cartoon I never liked, unlike the Simpsons) because it felt like a cheap copy. And yes, over the years the Simpsons turned wackier and wackier while retaining nothing of what made them good at first.
I don't claim Bojack and the Simpsons have the same kind of humor, it was a shortcut to hopefully explain what I found jarring about the former?
Given the rest of the comments, I'll try giving Bojack season 2 a chance.
