CBS has based its new relationship fantasy “The Ex List” (8 p.m. CBS) on an Israeli TV hit. But they needn’t have traveled halfway across the globe to plagiarize. They appear to have stolen an idea much closer to home.

On “Ex,” the main character has a spiritual epiphany, then feels inspired to make a list based on her past actions and goes about changing her life. “The Ex List” is “My Name is Earl” with a whole lot more sex, better-looking people and an emphasis on hedonism and narcissism as opposed to karma and redemption. And it’s not nearly as smart or as funny.

A fortune teller informs 30-something Bella (Elizabeth Reaser) that she has already met and even dated her soulmate and that if she doesn’t track him down in a year, she will never marry.

Bella hangs out with a gang of good-looking and affluent Californians who have a lot of time on their hands. The show is shot in San Diego, where the weather is perfect to the point of tedium. An unexplained virus has eliminated every human over 40 or under 19 from existence.

In the pilot, Bella encounters a former boyfriend (Eric Balfour) whose weepy clinginess and emo singing style left her wanting. Seven years later, she discovers that he’s still bitter over their breakup and sings angry songs about her to enthusiastic crowds. This isn’t believable for a second, but it’s a welcome relief from an icky subplot about intimate hairdressing styles.

“Ex” tries to exude a grownup, casual confidence about its sexual subject matter but too often feels like a sitcom. It’s also wearisome to care about a completely self-centered central character and her self-centered friends.

¢ Amanda Tapping (“Stargate SG-1”) stars in the two-hour pilot of the 13-episode series “Sanctuary” (8 p.m., Sci Fi). She plays Dr. Helen Magnus, a collector of odd, doomed and dangerous mutant creatures.

“Sanctuary” depends almost entirely on digital technology for its elaborate sets and fantastic creatures, so most of the “acting” is done in front of a green screen. The results are often deadly and reminiscent of those painful “Star Wars” scenes in which characters (and audiences) tried really hard to be interested in what Jar Jar Binks was saying.

¢ Speaking of George Lucas, the saga continues with the new series “Star Wars: The Clone Wars” (8 p.m., Cartoon Network).

¢ An artist (Rives) and a model (Bar Refaeli) go on a series of thematic road trips at the behest of designer Tommy Hilfiger on “Ironic Iconic America” (7 p.m., Bravo). In addition to a cliche travelogue (driving a red Cadillac to a Vegas wedding chapel, etc.), the artist and the model share a fake flirtation that borders on creepy.
