9PM TLC
Series finale
Jon & Kate Plus 8
It may have seemed like the season that would never end, but it's finally here. In the series finale, Jon and Kate are reconciling their separate lives yet shared parental roles. And how exactly do they do that? Why with respective visits to a dairy farm and a fire station, of course. Kate and the kids learn about farm life and cattle, while dad and the brood get lessons in fire safety and help raise money for local firefighters. Let's hope it's a worthy sendoff for the show that many grew to love and then loved to hate.

9:30PM-10PM ABC
Season premiere
Find My Family
The producers of Extreme Makeover: Home Edition have cooked up another tear-jerker series, minus Ty Pennington and any bullhorns. Instead, Find My Family has long-lost relatives and weepy reunions at the show's ''family tree.'' In the 30-minute premiere (future episodes will normally be one hour long and feature two families), Green and Joyner Steinpas are introduced to the daughter they gave up 27 years ago. Cold, stony hearts may scoff at the mushy plot and abundance of hugs in the show (*scoff*), but Makeover fans will likely just dive straight into their tissue boxes and enjoy.

8-9:01PM ABC, TV-14-V

Criminal Minds
Minds celebrates episode 100 by tying up its recurring Boston Reaper plotline and giving the killer (guest C. Thomas Howell) one last stab at Agent Hotchner (Thomas Gibson). It's gory, even for Minds, but the result is bloody good. You won't want to be alone again. A– — Aubry D'Arminio

9-10PM Fox, TV-14-D

Shameless
It’s so cute how the Brits think they can top our lowbrow humor with this tacky and profane family comedy. I have four words for them: Married. With. Children. Reruns.

9-11PM Syfy, TV-14-V
Beyond Sherwood Forest
Robin Hood (Robin Dunne) and his band of Merry Marxists take a break from their wealth-redistribution activities to go supernatural, tackling mystical portals, druidic orders, and that same giant lizard that appears in every other Syfy original movie. Maid Marian gets a healthy injection of girl power, carrying a big stick and not speaking softly. But other than that, the characters and story haven't changed all that much, so the fantasy bits feel about as incongruous as the towering Little John's moniker. It's as if the BBC's Robin Hood has been invaded by the otherworldly denizens of Doctor Who. C+ — Keith Staskiewicz

10-11PM CBS
