“Friday Night Lights” (9 p.m., DirecTV Channel 101): After five amazing seasons, the big-hearted, small-town drama, “Friday Night Lights,” ends its run. Several familiar faces return for the poignant finale, but we’ll hold back on the spoilers out of respect for fans who won’t see it until it airs on NBC in a few months.

“MR. SUNshine” (9:31 P.M., ABC): An old friend returns in the new sitcom, “Mr. Sunshine,” as Matthew Perry stars as the self-centered manager of a sports arena. We’re just praying that it’s better than “Joey.”

“Justified” (10 p.m., FX): In Season 2 of the riveting drama, “Justified,” Deputy U.S. Marshal Raylan Givens (Timothy Olyphant) continues to walk tall and wear a big hat. Our advice to bad guys: Don’t get in the way of his six-shooter.
