Season 2 of Covert Affairs starts tonight on the USA Network. I was mildly entertained by Season 1, but Covert Affairs is not must-see TV. However, Piper Perabo as a C.I.A. agent Annie Walker delivers earnest performances and the cast that surrounds her (Peter Gallagher as C.I.A. Chief, Kari Matchett in her cocktail dresses as Annie’s boss, and Christopher Gorham as Annie’s blind colleague) is surprisingly strong for a cable show with a limited budget. Hopefully, the scripts in Season 2 will be stronger than Season 1.
