"Win a Date with a Celebrity" does strike me as new, but aside from the fact it's total garbage, there are two big flaws.
It seems the whole conceit is the celebrity going out with whomever they picked unseen. It turns out they each get three picks of the unseen women, then choose after all the reveals. Way to kill the big moment.
And it doesn't appear there's any Love Connection-style catch up after the date. Why Fox would blow that opportunity is beyond me.
