How bad is public school?

I've been homeschooled my whole life apart from college dual credit stuff, and so i have very little knowledge of what public school is like. Is it really as bad as they say?

So far, apart from screenwriting, I've never felt overworked with school. The only other four college classes I've taken were pretty light feeling workloads and never got very difficult. And of course homeschool is homeschool so it's very little work as well.

So how bad is public schooling? Would you consider it closer to an inconvenience or an overbearing weight that has major negative effects on your life?
