Those under-appreciated shows that only you and Mama could love — past and present — get their places in the limelight this week:

“Private Practice” (Tuesday, 9 p.m., ABC) The Seattle Grace spinoff finally gets out of the shadow of originator “Grey’s Anatomy,” moving to a new night. Here’s hoping the new time slot will help distance us from Meredith (Ellen Pompeo) and Derek’s (Patrick Dempsey) “House Hunters: Seattle” and let us focus on the maybe-baby drama for Addison (Kate Walsh) and Sam (Taye Diggs) after a gloomy season.

“Veronica Mars” (Sunday, 8 a.m. to 7 p.m., SOAPnet) The network named for a dying genre introduces the canceled CW teen detective show — Mama doesn’t exactly predict blockbuster ratings. Too smart and witty to be successful, Veronica (Kristen Bell) invades the network with an all-day marathon today, and airs twice a day Monday through Friday and three times a day on the weekend. So now there are no excuses for missing this overlooked series.

“Eureka” (Monday, 9 p.m., Syfy) As the town of geniuses launches its fifth and final season, Allison (Salli Richardson-Whitfield) is stuck aboard a disappearing spacecraft with a bunch of the other misfits. Four years of watching a town filled with geniuses making bone-headed mistakes leaves little reason to wonder why this show doesn’t get much love.

“Castle” (Monday, 10 p.m., ABC) The quick-witted detective show wouldn’t normally make the list of shows that get no respect. But this week’s guest star, Adam Baldwin, formerly appeared with series star Nathan Fillion on TV’s most underappreciated drama, the DOA but fantastic sci-fi adventure “Firefly.” The great grunter Baldwin reunites with Fillion as Castle’s new partner, introducing the writer to the grittier side of police work.

“Fringe” (Friday, 9 p.m., Fox) There’s probably some perfectly geeky explanation for why “19” is important (and no, you don’t need to e-mail Mama and tell her what that reason is — I don’t really care), but every season’s 19th episode of the twisty sci-fi series takes a more bizarre turn than usual. This year, the Fringe team jumps ahead to the year 2036, which is about when Mama expects to be able to grasp half of what they’re talking about on on this show.
