“Couples Retreat” — Four troubled couples make a week’s retreat to an island paradise where they hope to be healed, which indeed happens, according to ages-old sitcom formulas. The jolly ending is agonizing in its step-by-step obligatory plotting. Starring Vince Vaughn, Jason Bateman, Faizon Love, Jon Favreau, Malin Akerman, Kristen Bell, Kristin Davis and Kali Hawk. DVD Extras: Extras: Director/Vaughn commentary, alternate ending and deleted/extended scenes (with commentary), three behind-the-scenes features and bloopers. Rating: Two stars. (PG-13)

“A Serious Man” — The darkly comic new Coen brothers film. Every single thing in Larry Gopnik’s life is going wrong. His wife is leaving him for his best friend. His son is misbehaving in Hebrew school. His daughter is stealing money. His brother-in-law is sleeping on the sofa. His neighbor is a gun nut. A student tries to bribe and blackmail him. There’s worse. Larry teaches advanced physics, but his life is a medieval tragedy. In a 1960s Minneapolis suburb, the Coens restage the Book of Job as rich human comedy. DVD Extras: Extras: Three behind-the-scenes features. Rating: Four stars. (R)

“The Time Traveler’s Wife” — Clare (Rachel McAdams) is in love with a man who frequently disappears into thin air, leaving behind his clothing in a pile on the floor. Henry (Eric Bana) is a time traveler whose trips are beyond his control. Another problem is that whenever he arrives at another time, he’s naked and has to steal clothes. You’d think he’d be demoralized, but somehow the warmth of the actors makes it a bittersweet love story. Information on “DVD Extras” was not provided. Rating: Two and a half stars. (PG-13)
