Every review I have read for this show has been completely negative. I really don't understand what people didn't like. I thought it was pretty good. Mike O'Malley is a really good actor, and the cast seems to be having a fun time.
Every critic is calling it a "culture clashing" show. They could not be more wrong. Yes, there are two families, one latino and one white, but that is not the point. The cultures aren't clashing, O'Malley and Ricardo Chavira's characters are clashing. They don't like each other, but race has nothing to do with it. Class has a little bit to do with it, but it's mainly a show about two people who can't stand each other, but now they're in laws. Everyone is calling it an All in the Family ripoff, but at most it's an Odd Couple-ripoff, which there have already been about a million of. Not that there's anything wrong with that.
I've heard people say it's a racist show? How? There was nothing racist about it. I've heard people call it "broad comedy". But there's no laugh track, physical humor, or over the top performances! If anything, it might be a little bit too low-key. I liked it a lot, and I am not normally a big fan of family comedies.
Bottom line, it's not great, but it's good. Ignore the critics, check it out for yourself.
