Other reality shows have used the same format, including
The Ultimate Fighter -- which gives up-and-coming mixed-martial artists the chance to win a contract to fight for the UFC -- and
The Contender, which offered young boxers a large cash prize and the opportunity to get noticed. But these series focused on unknowns who've been training for years and desperately want to succeed at their sports; for them, landing a spot on one of these shows is a huge break.
But the Celebrity Wrestling participants have no background in the ring, and it's not clear they even have much desire to be wrestlers. Their moves aren't convincing, and the staged brawls are unlikely to satisfy either wresting supporters, who'd probably expect a better show, or reality show fans, even if they're usually willing to tolerate even the most contrived situations. Since the show never mentions any kind of cash prize (nor is the winner promised a pro wrestling contract or any other kind of reward), it's not clear what the contestants are hoping to gain -- other than bragging rights and attention. But maybe that's all they want.
