Those shows are eye candy for DIY Homeowners who don't understand what they're getting into, or the reality of what is really going on. The show producers put lipstick on a pig, hug the homeowners, cash the sponsor's paychecks, and move on to the next project. I've always wanted to revisit the house a few years later, and find out what it had been like for the homeowners, living in the remodeled home.
Remember this? Way back when, on "Trading Spaces," when designer Hildi Santo stapled more than 7000 fake flowers to the walls of a bathroom? I can only imagine what a horror that would be to live with - or clean.
Don't get me wrong, I love a good renovation, and have taken on a few of my own over the years. But I agree with
@joestein's comment, that it is never as easy (or as cheap) as it seems.
Sometimes you have to question the honesty of what is presented. One of my favorite home-improvement shows is called "Restored," where skilled host Brett Waterman updates and restores classic homes in the Redlands, California area. The homes are iconic, most are greatly improved at the episode's end, and the show is really fun to watch. But he did a home for his close friend and his new wife, giving them the dream home the husband said he had always wanted. It turned out beautifully. But then, the next season, the friend/husband was back, with a new home, and a new wife, for another dream home makeover. The husband came across as a thinly-disguised house flipper, and it kind of watered down the appeal of the show. (Although the workmanship seemed to be top notch.) I know life happens, but it was too soon for a do-over on the husband's life. It didn't seem real.
