'Real Housewives of O.C,' been there Truth is, the spinoffs are more entertaining to watch than the original, whose characters and storylines are now predictable   'V,' lost in space in a trip back in time ABC sci fi drama, a remake of a 1983 mini-series about an invasion of earth by aliens, moves quickly, perhaps too quickly   'Big Bang Theory,' in the sweet spot Ratings are way up for the CBS sitcom, now in season three, as the show's writers and actors settle into a groove   'Sex Rehab With Dr. Drew,' addicting VH1 series is not the snicker-fest you might think. One grows to sympathize with the patients who are undergoing treatment.   'Cougar Town,' better than you'd think The theme of older women with younger men is a tired one but this sitcom works because it reaches beyond. It's well done.   'White Collar,' cool if you're 14 or so USA copper pairs up an FBI agent and an ex-con in a crime-solving caper whose plot is as implausible as it is hackneyed   'The Jeff Dunham Show,' for dummies He makes them talk but what they say isn't funny. The new Comedy Central show is a throwback to the early years of cable.   'Living with Ed,' if you really must Imagine a sitcom about a couple trying to live green, but it's not a sitcom but a poorly scripted reality show. You've got it.   'Eastwick,' could use a bit of deviltry ABC dramedy based on the Updike novel falls flat, suffering from a weak script, cliched characters and one-liners that aren't funny   'NCIS: Los Angeles,' boys will be boys CBS spinoff is about two buddies goofing around and cracking wise as they solve crimes with neato stuff like fast cars next >>
