Funny this show has a lot of low ratings because most of the people I know love this show and most of the people who reviewed the show here enjoys it as well. And the ratings on IMBD are not bad (7.7 as I write this)
My theory is maybe a certain number of "Everybody Loves Raymond" fans were pissed at Romano's new show cause it wasn't a comedy and they decided to give very low ratings (probably 1 or 2) to every episode. If 15 person did this, it's easy to tank a global rating.
That's the only explanation, but who cares, it's a great show and I still enjoy it.
