In all honesty, it gets better as it progresses. The humor definitely isn't for everyone. Much of the humor plays on itself, with references and throwbacks to past episodes.

And tbh I just feel bad for Michael, the rest of the family is insufferable.

That's also part of the charm of the show ... the entire family is terrible and Michael tries to do good by his son while also attempting to be a caring family member. I'd recommend to give it a bit more time before you give up entirely. There are lots of cameos from other actors (Henry Winkler, Liza Minelli, Charlize Theron) and you have the great Ron Howard as the narrator. If not, no biggie.
