SUPERHEROES AND CELEBRITY WORSHIP

Tonight, Taye Diggs and Demi Burnett hog the spotlight once afforded to ordinary people on “The Celebrity Dating Game” (10 p.m., ABC, TV-14).

This cancer has overtaken HGTV, once a bastion of ordinary folks doing mundane chores. Programmers believe that viewers would rather watch the famous promote themselves than learn anything practical about landscaping or drywall.

This brings us to something called “Celebrity IOU,” a 21st-century variation on “This Is Your Life,” a chance for the very famous to reach out to the “little people” who helped them on the way to the tippy top.

Tonight’s second installment (9 p.m.) features singer LeAnn Rimes helping a friend who helped her through a dark patch. Fair enough. But the first (8 p.m.) sees actor Jeremy Renner (“The Hurt Locker”) renovating his mother’s outdated condo. We’ve reached a point where a rich celebrity helping out HIS OWN MOTHER is considered deserving of our adulation.

I’m getting the sneaking suspicion that the folks who own HGTV (and its sponsors) don’t exactly respect their viewers.
