It's fine, it's good - unless you have particular hangups. If you're NOT American, you can safely ignore all the negative reviews about this.
I have watched every episode. It's fine, it's well-scripted, it's rather formulaic, but consistent and varied enough, it has character development that gets a bit long-winded at times, and it tackles relevant local issues (which make much of the world cringe in horror of what the US has become). It's no Brady-Bunch, but it models personal responsibility, hard work, consideration of others, difference of opinion, and seeking solutions rather than staying dysfunctional in the problem.
But there's a portion of the local market that hates any portrayal of weakness, vulnerability, morality, tolerance, or problem-solving; they can't cope with an opinion different to theirs, and so they're lowering the overall ratings. They seem to think that the plot, scripts, and topics of a TV series is somehow incendiary and political.
Maybe it is for the locals, but for the rest of us, just ignore those negative reviews, and enjoy this series.
