Critic's corner

House 8 p.m., Channel 25

Tonight's episode, which is 68 minutes long, features Zeljko Ivanek as a gun-wielding patient who demands treatment. I am definitely onboard for this one. Ivanek, who won a supporting actor Emmy for "Damages" this year, is one of those dynamic actors you've seen all over the place - on "The Mentalist," "24," "Lost," "True Blood," and "Oz," to name a few of his credits. And he's usually effectively creepy (although his Southern accent on "Damages" was excruciating).

The Shield 10 p.m., FX

This is the end, my friends. The dark, intense cable series finishes its seven-season run tonight, with a special 90-minute episode. Michael Chiklis has been chilling as Vic Mackey, a good cop gone very, very wrong, the personification of corruption and anarchy. The big question is, will Vic get his comeuppance in the end?
