The USA Network's motto is "Characters Welcome." Apparently they're especially welcome if they resemble Oscar Madison and Felix Unger. Already stocked with Odd Couple knockoffs in Psych and White Collar, USA adds to its inventory Common Law, another comic crime-fighting show about mismatched partners. But this latest entry exhibits very little of that kind of spark as it tries to wring laughs from the juxtaposition of counseling and police work. It looks too flat and schematically plotted to succeed as the type of lightweight summer fun we’ve come to expect from USA.

Johnny Carson: Fantastic entertainer, miserable human being. That's the lasting message of Johnny Carson: King of Late Night, the new PBS American Masters film, a rich history of a rare product of television who dominated the small screen for decades. Unprecedented access to personal archives plus all existing episodes of The Tonight Show (1962-92), distinguishes this film by Peter Jones. Telling interviews with family and colleagues, including second wife Joanne Carson, former Tonight Show executive producer Peter Lassally and a number of biographers sharpen the picture. The clips are carefully selected to illustrate specific personality traits, the performance highlights are given context and meaning beyond funny lines and memorable moments.

AMC's The Pitch is a sharply-made if slightly off-putting reality series that follows different advertising agencies each week as they compete for new accounts. The inspiration for the show — made clear by its own ad campaign — is to harness some of the verve generated by the network's acclaimed Mad Men. The Pitch has a way of making the ad world seem like a real downer — a repugnant exercise in egotism laced with depressing bouts of creative compromise.

HBO's Veep stars Julia Louis-Dreyfus as former Sen. Selina Meyer, who accepts the vice presidential duty and regrets it almost immediately: She has no real power and gets muscled by the Senate, Congress and the (so-far-unseen) president, who delegates all the truly crappy jobs to her. Louis-Dreyfus has found perhaps her best post-Seinfeld role and takes to it with such fervor — the constant swearing, the barely veiled desire to become president, the unhappy give-and-take with other politicians and a delightful disdain for average citizens — that you can't help but applaud what is clearly an Emmy-worthy effort. Her work alone makes Veep a gem, but there's even more to like.
