SUNDAY'S MUST-SEES

"Extreme Makeover: Home Edition," 7 p.m., ABC; and/or "Nick News: Coming Home: When Parents Return From War," 6 p.m., Nickelodeon. Both shows tell of soldiers returning home from Iraq. A Kansas man lost his leg during his second hitch in Iraq. Now the "Extreme Makeover" team rebuilds his home. Meanwhile, "Nick News" looks at the broader picture of waiting for a parent. Like other Linda Ellerbee productions, this is thorough and honest. It views soldiers who returned unharmed and ones who were seriously wounded. It also takes an unflinching look at post-traumatic stress and the parents who retreat into solemn silence.

SUNDAY'S MIGHT-SEES

"Happy Feet" (2006, 4 p.m.) and "The Simpsons Movie" (2007, 6 p.m.), HBO. The weekend wraps up with an animated double feature. First are dancing penguins, then talking Simpsons. Like the TV "Simpsons," the movie is erratic, with hilarious moments.

Olympic Trials, 6 p.m., NBC. We're to the finals now in swimming and track-and-field.

"Factory," 7, 7:30, 9 and 9:30 p.m., Spike (Oceanic Digital Channel 559) Blue-collar comedy series are rare, so let's try this one. It focuses on four likable co-workers. Tonight, one buys a car and another wants to propose; both plans go astray in fairly funny ways.

"Million Dollar Password," 7 p.m., CBS. Things turn youthful, with MTV's Damien Fahey and "High School Musical" co-star Monique Coleman.

"Masterpiece Mystery: Inspector Lewis: Expiation," 8 p.m., PBS. After two excellent tales, "Lewis" goes overboard with its final story of the season. A well-liked Oxford housewife kills herself. That leads to a dizzying excess of secrets and deceptions.

"Baseball's Golden Age" debut, 9 p.m., Fox Sports Network. This show spends way too much of its half-hour hyping itself, telling how it's using color film from way back. That's true and once we get to the good stuff — the actual film, the memories of players and fans — it's engaging.
