Series premiere tonight at 9 on E!

“Bridalplasty” just might be the most depressing TV series ever to air on television.

In this unscripted competition on E!, 12 brides-to-be are isolated for four months in a luxurious mansion and compete in a series of challenges to win plastic surgery procedures. After each challenge, the brides cut one of their own.

Last bride standing wins a full body makeover and a celebrity-style wedding.

“If you’re going to have a dream wedding, then you want a dream body,” bride-to-be and hopeful patient Alexandra says in a typical exchange that plagues this “Stepford Wife”-like show.

E! released a DVD for review but withheld the final elimination sequence, and I have a firm rule never to grade a show when a network cheats on a screener. But I’ve never been so sorely tempted to stamp a big red F on its ugly forehead.

This is about as repulsive as reality TV gets.

The women, for those curious, are for the most part gorgeous.

Ashley can’t understand why so many skinny, umm, witches are in the competition. Of one, she says, “I could swallow her, seriously, and you wouldn’t even know. ‘Oh, are you bloated?’ ”

They’re just unhappy in their own skins and are convinced plastic surgery - several rounds, to be exact - will solve all their problems.

Right. Because reality shows are renowned for solving self-esteem issues.

Alexandra was a former contestant on NBC’s “The Biggest Loser,” where her fiance proposed to her on national television. Her bragging puts a bull’s-eye on her butt.

Kristen is a former beauty pageant winner. “I have more than enough experience competing with women,” she says. Dominique reports that her parents spent all their money on a dream wedding for her sister and left nothing for her. “It’s very sad for me,” she says.

E! apparently found these women through a black hole that leads to the 1950s.

Home videos introduce us to some of the men in these women’s lives. They range from skeptical to enthusiastic for the procedures. One grins at the thought of his intended undergoing breast augmentation.
