Pretty good. Not great.
If that sounds "incredibly shady" and "what the hell dude, no" to you, good news! You're a human being with a functional moral compass. That puts you above the producers of this show. One of the contestants was Sarah. According to her, the whole "not really a millionaire" thing wasn't where the surprises started. Fox went out of their way to hide the basic structure of the show from the women.
"And they also give you these contracts at the laaaaast minute, and you don't have time to get them reviewed. It's all a trick. Everything was a lie. I remember I had one of the female producers say to me, I kept trying to get information out ... we were told it was not a dating show, but you had to be single so that you'd be open -- what if you meet someone? Y'know, anything like that, but we were never told it was a dating show."
At one point, Sarah was told it was a cooking show. Sloppy Joe Millionaire! Brilliant! "Y'know, they said everything. Everything but a dating show." Sarah was a law student in Los Angeles. The producers said that, in part, was why they were interested in her. "They said, 'We're only casting professional women. The show was for role models, for little girls, we want really strong women.'"
Evan and the "winning woman" were each supposed to walk away with $500,000 at the end of the series. The more cynical among you might think that was why Sarah signed up to be on the show, but it turns out they also hid the fact that there was any prize at all. "We didn't know that there was any prize money, so it certainly wasn't a factor ... they just don't tell you anything until you're super hyped that you've just been cast on this awesome show, and it's this free trip to France with these other amazing women, and it's gonna be great, and a good, positive show."
Sarah got the contract 24 hours before she left for France. "They keep saying things like 'We're not sure you've got the part yet' ... they don't want you to have any advice."
