This was never the kids' choice
Say the kids force Suzanne on him even though he made his favorite quite clear and was quite vocal about it.
Are they really going to sit on the couch and cuddle while watching Who Wants to Marry My Dad on TV ? Come on.
That's why the premise of this show never made sense to me. If the kids pick a woman the Dad isn't totally infatuated with, she's going to be quite aware of that fact as soon as she begins watching the show.
...isn't that what happened with the last Who Wants to Marry My Dad ? The kids forced the little old lady (forget her name, sorry...) on the bald Dad and sent away the busty former beauty queen. Well, what woman would tolerate knowing that the man she's with only considered her an inferior second choice (...at best)?
There's no way the kids could ever impose their will: their Dad might grudgingly consent to it; but the woman that they force him to pick? No matter how much she might love him (or his money), could she tolerate knowing where his heart truly lies ?
