Leverage 9 p.m., TNT
I wanted to love this show last season, because I am a fan of con-artist stories and the cast is so likable. But I was consistently disappointed by the poorly constructed con plots. Compared to the clever and similar British series “Hustle,’’ the “Leverage’’ stories were weak. The show, starring Timothy Hutton (above), returns tonight for season two with the cast as charming as ever but still the plot is totally stoopid. By the way, the gang is now based in Boston, although the show is filmed in Portland, Ore.
Monsters Inside Me 9 p.m., Animal Planet
A show about parasites? Gross. And tonight’s special topic re-creates an attack by bed bugs (above). Yeah, really gross. But tonight’s episode also features Stephanie Gould, a young actress originally from Melrose. And that’s truly not gross. Gould, who was in “Kings,’’ will also appear in a couple of episodes of “Rescue Me’’ later this season.
