Best bets: Happy trails to J.R. Ewing

Larry Hagman's J.R. Ewing made an indelible mark on television history. His final episodes on the new version of "Dallas" start this week. More familiar faces: Keri Russell has a new show, and Al Pacino, Christopher Walken, and Alan Arkin have a new movie.

MONDAY: 'Dallas' returns
J.R. Ewing was one of television's most captivating villains on the original run of "Dallas," and he was the reason the show's return in 2012 was so well-received. The cowboy hat-wearing oil baron was conniving and charming, and it's impossible to imagine anyone but Larry Hagman playing him. Now that Hagman has died, the show must bid farewell to J.R. in a deserving manner. He couldn't ever be recast. The cast and crew of the new "Dallas" have promised to make his on-screen funeral one to remember. Happy trails, J.R. ("Dallas" returns with the first of Hagman's final two episodes Jan. 28, 9 p.m., TNT.)

WEDNESDAY: 'The Americans'
FX's new show, "The Americans," has a delightfully creepy, if dated, premise. Back in the 1980s, the KGB has settled a bunch of its agents in the U.S. as sleeper agents, even with unsuspecting families. Keri Russell (hi, Felicity!) and Matthew Rhys are a spy couple with kids who don't suspect Mom and Dad are Reds. USA! USA! (Premieres Jan. 30, 10 p.m., FX.)

FRIDAY: 'Stand Up Guys'
They're senior-citizen criminals, geezer gangsters. In "Stand Up Guys," Al Pacino and Christopher Walken play old buddies in crime who team up once Pacino gets out of prison, and also meet up with their former getaway driver, Alan Arkin. Reviews are mixed -- some critics think it's an unfunny slog of Viagra jokes -- but those are three veteran stars who command attention. (Opens Feb. 1.)
