Lots Of Grand Finales On Television This Week

It's the biggest week of the year for TV series finales.

Dozens of shows say farewell for now, either by tying up their action or leaving stories gaping wide open with cliffhangers.

Prominent among them tonight is the finale of "Brothers & Sisters" (ABC, 10 p.m.), which promises a resolution to its most recent crisis (a brother missing in Mexico, even before flu is detected).

The second half of a two-part murder case on "Cold Case" ( CBS, 9 p.m.) closes that show's season. And a nuclear crisis is part of the fourth-season finale of "The Unit" (CBS, 10 p.m.).
