DRAMA
NCIS: Los Angeles
CBS, Global, 9 p.m.
Back tonight for a third season, this sturdy crime procedural has built a loyal viewer following on Tuesday nights. In the beginning, the show focused primarily on the special projects branch of the Naval Criminal Investigative Service, hence most of the stories involved espionage or terrorist threats. Forty-odd episodes later, the format now spends more time on the personal stories of the NCIS stalwarts. Case in point: Tonight's show takes special agents Callen (Chris O'Donnell) and Hanna (LL Cool J) to Romania in a frantic search for their operations manager Hetty (Linda Hunt). We should all have such considerate co-workers.
