GRIMM
NBC, 9:00 p.m. ET
MIDSEASON RETURN: Not since The X-Files carved out a large and loyal Friday night following on Fox has this night been a springboard for genre series, rather than an impatient launch pad for eventual cancellation. (Think Fringe. Think Dollhouse. Think of a lot of shows.) Well, even though the prospects may be grim, here comes Grimm, returning at midseason, picking up where it left off. And where did it lead off? With two of its characters, Renard (Sasha Roiz) and Juliette (Bitsie Tulloch), under a mutual love spell cast by a witch. Their judgment, like the photo, is a bit blurry.
