Watch it

“Survivor: Redemption Island” (8 p.m., CBS). While everyone’s off watching “Idol,” “Survivor” is quietly having a really intriguing season so far. And how sweet was it so see Russell voted off so quickly? Tonight, he and Matt will duel on Redemption Island in a good-vs.-evil struggle to stay on the show.

“Top Chef All-Stars” (10 p.m., Bravo). The final five head to the Bahamas to face the chefs who beat them in their respective seasons. Later, they cook for Bahamian royalty. Don’t look for any double eliminations after last week’s surprise non-elim — there are still three more episodes left after this.

Record it

“American Idol” (8 p.m., Fox). The finals start with the final 13 singers.

“Justified” (10 p.m. FX). Raylan goes on loan to an organized crime task force, Boyd gets involved in a payroll heist and Pa Givens is arrested for violating his house arrest.

“Face Off” (10 p.m., Syfy). The five remaining special-effects artists must disguise themselves well enough to fool family members. I don’t know if anyone’s been watching this, but it’s been a pretty entertaining series.

Skip it

UPDATE: “Real World” (10 p.m., MTV). Season premiere. I forgot all about this, which tells you all you need to know. One nice thing about “Jersey Shore”: It’s made “Real World” irrelevant. This time they’re in Las Vegas again, but really, who cares anymore?

“Charlie Sheen’s Winningest Moments” (10:30 p.m., Spike). A cheap, hastily thrown-together clip show to cash in on Sheen Mania. Don’t bother.
