CBS got rid of its nervy caper show Smith after three episodes, just disposed of it like a bad lab sample, and now has brought in a fairly routine medical drama. 3 Lbs.—the title refers to the weight of the human brain—stars Mark Feuerstein as an idealistic young neurosurgeon named Jonathan Seger. He's just been hired by the willfully impersonal but incisive and brilliant Dr. Hanson, who heads a Manhattan clinic so successful it doesn't look all that different from the luxe fashion-magazine offices in Ugly Betty. Stanley Tucci plays Hanson without overdoing the sniffy arrogance, and Feuerstein administers Seger's warm decency carefully—no overdosing on sentiment. Still, other than graphics that scoot along the neural pathways like subatomic Nascar racers, the show doesn't have much new to offer.
