Ok this is supposed to be family tv? It could be but there is a constant barrage of sexual innuendo. The thing is that it's not necessary. The show will be rolling along with a nice family message and suddenly there it is. SEX! No reason why. not really necessary to the story but they just insert it. I don't understand because it comes off as a family show otherwise. Lets not forget the ocassional cuss word either. If your kids 14 it probably won't hurt them unless they been home schooled and are extremely sheltered. The messages are usually positive.
My Wife and Kids is one of the best shows in its kind. They always make me laugh with the remarks that they made to all their friend and family members. This show is for all kinds of ages and it's mostly suitable for families. It is all well acted by all the actors and they do their best to make the show exciting, well written and funny.
I don't believe this show is age appropriate for 11-14. This show is geared more toward what happens in a marriage, i.e. jealousy, sex, adult language between adults, and raising children. The focus is on the marriage... hence the title of the show.
The sex jokes, which are often put in out of the blue for no good reason, make this series questionable for children under 13. But that's not the main problem of the show. Its main problem is that one character is always trying to upstage all the others. In the process the storylines and the messages usually get lost.
