Loved Season 1 & 2, but started watching S3 and lost interest

I don't know why, but they seemed to be taking it too
seriously, or something. I can't bring myself back to
watching it. I can only take so much of watching jerks
like Jimmy abuse people. That is all we see on TV and in
the movies these days, killing, violence, abuse and mean
jokes. How can anyone possibly think it is a coincidence
that our society is so full of violence?
