Saturday on TV

Final Approach (6 p.m., Hallmark): You could call this movie Airport 2008 — it's a big, barely believable adventure set on a hijacked airliner. And it features a bunch of has-been stars (like Dean Cain, Lea Thompson and Tracey Gold). If you disengage your brain a bit and sit back and watch it, it's not bad. (It also airs Sunday at 11 a.m.)

MLS (6:30 p.m., Ch. 5): Real Salt Lake at FC Dallas

NBA playoffs (6:30 p.m., Ch. 4): Boston Celtics at Detroit

Pistons

AFL (7 p.m., Ch. 14): Chicago Rush at Utah Blaze

Sunday on TV

Auto racing (3 p.m., Ch. 13): The Coca-Cola 600

Shark Swarm (6 p.m., Hallmark): Final Approach isn't horrible, but Shark Swarm is. It's just an atrocious TV movie about a bunch of white sharks killing people.

NBA playoffs (6:30 p.m., TNT): Los Angeles Lakers at San Antonio Spurs

Dateline (6 p.m., Ch. 5): Helping Army veterans heal their psychological wounds.

National Memorial Day Concert (7 p.m., Ch. 5): Gladys Knight, Sarah Brightman, Colin Powell, Idina Menzel, Denis Leary, John Schneider, Gail O'Grady, Charles Durning, Rodney Atkins, Caitlin Wachs and the National Symphony Orchestra perform.

The Unit (9 p.m., Ch. 2): Repeats of this series begin airing in a new time slot — the one it will occupy in the fall when new episodes begin.

Recount (10 p.m., HBO): Amusing, involving, aggravating retelling of the battle over the 2000 recount battle in Florida after the contested election between George W. Bush and Al Gore.

The Tudors (10 p.m., Showtime): Anne's fall from grace is swift and complete.
