As far as reality genres go, the past-their-prime celebrity inviting cameras into their home to drum up some publicity is overdone, to say the least. So how do this summer's entries, the new Hammertime and the fourth season of Gene Simmons Family Jewels, fare? Let's take a look.

As far as reality genres go, the past-their-prime celebrity inviting cameras into their home to drum up some publicity is overdone, to say the least. So how do this summer's entries, the new Hammertime and the fourth season of Gene Simmons Family Jewels, fare? Let's take a look.

The star

Family Jewels: Gene Simmons, the tongue-wagging Kiss frontman. Kiss' popularity peaked in the 1970s, but still tours. Simmons spends his time making Kiss-related appearances, hitting on women and devising ways to capitalize on his fame.

Hammertime: Stanley Burrell, aka MC Hammer, the '90s relic known for his mega-hits "U Can't Touch This" and "Too Legit to Quit," his spectacular fall into bankruptcy, and his pants. These days, Hammer makes money as a web mogul.

The significant other

Family Jewels: Actress and model Shannon Tweed, Simmons' longtime girlfriend, rose to fame as an early '80s Playmate. Still luminous at 52, she appears smitten with Simmons despite his aversion to marriage and is an affectionate mother. She's goofy and outspoken and can spend money faster than anyone you've ever seen.

Hammertime: We don't learn much about Hammer's longtime wife Stephanie during the first episodes, besides that she's remained devoted to him through the ups and downs and that she spends her days caring for their five children and a nephew. Hammer: "It doesn't get any better than this. My best friend is my wife."

The kids

Family Jewels: 20-year-old Nick and 16-year-old Sophie are smart, funny and well-adjusted, and they offer pitch-perfect observations on their parents' shortcomings. Nick's an aspiring musician, Sophie an aspiring model. I have a feeling they'll both be stars one day. And not the kind of tabloid train-wreck stars celebrity kids usually turn out to be.

Hammertime: There's college student A'Keiba, budding singer Sarah, Stanley Jr. (inexplicably nicknamed Booby), 11-year-old Jeremiah and Sammy, the baby of the family. None are comfortable on camera. Hammer tries to keep them grounded with warnings like, "They're not gonna give you no break because you're Hammer's son."

Running bit

Family Jewels: Old family videos, most featuring Nick and Sophie as adorable tots.

Hammertime: Hammer's Twitter updates flash on the bottom of the screen.

Best reason to watch

Family Jewels: A la The Osbournes, the appeal is seeing how rock stars live their daily lives. With plenty of crazy exploits and tons of charisma, this family is tailor-made for TV. The only reason this show's not more popular has to be its cringe-inducing name.

Hammertime: This borefest's only draw is nostalgia. If you were a huge Hammer fan, you might enjoy scenes like a spring cleaning that unearths his debut album, Feel My Power, and a jacket from a music video. (He didn't save a single pair of Hammer pants?!)

In short

Family Jewels: They're just like a normal family, except everyone's attractive, articulate and interesting. Grade: B+

Hammertime: They're just like a normal family. So much so that it's pretty boring to watch them. Grade: C-
