Kourtney and Khloe Take Miami (E!)

In KOURTNEY AND KHLOE TAKE MIAMI, West Coast sisters Kourtney and Khloe Kardashian move east to the "Party City" to open up a new branch of their upscale Dash boutique. Their sister, Kim, makes an appearance from time to time. But the focus is mostly on how these stylish sibs balance business matters with their busy social lives (they party a lot) -- and Khloe's side career as a late-night radio talk show host.

Trying to force a spin-off from a show that wasn't that good to begin with might have seemed like a good idea to producer Ryan Seacrest. But for most viewers, Kourtney and Khloe Take Miami will be a lukewarm guilty pleasure at best. The show's thinly veiled attempt to drive traffic to the sisters' pricey boutique is practically transparent, and they're ultimately not that interesting to watch.

It's a shame that the Kardashian sisters' party-hard lifestyle -- and the iffy behavior that comes along with it -- takes away from their more admirable qualities. They clearly have at least some degree of business savvy, and that's a great thing for teen girls to see. But Kourtney and Khloe seem far more interested in clubbing, shopping, and acting up for the cameras -- and looking impossibly fabulous while doing it.
