OMG. I just saw a commercial for this on FOX (who else would do something this bad?). It looks awful.
The premise is that this girl comes home with this big fat obnoxious fiance' (thus the name of the show) & they are planning a wedding & the guy is totally disgusting & her family is against the marriage. If she goes through with the wedding, she will get a million dollars (unbeknownst to the parents, of course). I don't know if the "fiance' " gets anything. The guy is in on the "joke" with the girl, but the family doesn't know it's not for real.
I, for one, am sick of "reality" shows making a mockery of marriage. They treat it like a joke & not a serious commitment. And then people wonder why the divorce rate is so high.
