Today on TV

90210 (7 p.m., Ch. 30): Last season, I got bored with this show and gave up on it. I watched tonight's second-season premiere and was lost —I have no idea what's happening. And I didn't particularly care, either. Which is not a good sign.

Warehouse 13 (7 and 9 p.m., Syfy): Pete, Myka and Claudia are trapped in the warehouse

Big Brother 11 (8: 01 p.m., Ch. 2): The veto competition is held.

Shaq Vs. (8 p.m., Ch. 4): Shaquille O'Neal takes on boxer Oscar de la Hoya.

America's Got Talent (8 p.m., Ch. 5): The second group of 10 finalists performs; six will be eliminated in Wednesday's show.

Melrose Place (8 p.m., Ch. 30): This is a revival of the '90s show, featuring a (mostly) new cast of young, beautiful people. I won't pretend for a moment that this is great drama, but it does have the makings of a trashy-but-fun soap opera.

10 Things I Hate About You (9 p.m., ABC Family): Kat organizes a protest over the school's new policy on uniforms and bag searches.

P.O.V. (11 p.m., Ch. 7): "English Surgeon" chronicles the work of a British neurosurgeon who has traveled to the Ukraine for 15 years to care for patients who have been left to die.

Sons of Anarchy (11 p.m., FX): In the second-season premiere, the club is divided in the wake of Donna's death.
