Nick Burkhardt (David Giuntoli), Portland’s trendiest detective (he sports designer jeans and chic leather jackets, no drab suits for him), has a gift. No, it isn’t his pretty eyes, though those baby blues do have something to do with it. Nick is a Grimm and can see fairytale monsters. More accurately, he sees “Wesen,” creatures with two physiological states—human and beast—who are the “real-life” basis for all of the animal characters and magical antagonists described in folklore and legends. Though Wesen appear to be ordinary people, Nick has the ability to detect the beast within and then shoot that beast in the throat with a crossbow if it pisses him off. Grimm, NBC’s gritty, supernatural crime procedural, was one of last year’s most addictive new series and an unexpected hit for the network. In the first season, Nick learned about Wesen with a lot of help from his new wine-swilling Blutbad bestie Monroe (Silas Weir Mitchell) while hiding his Grimminess (Grimmdom?) from his girlfriend Juliette (Bitsie Tulloch) and partner Hank (Russel Hornsby). The season was fun and spooky, perfectly capturing the darkness of the original Grimm’s fairytales without regurgitating those stories. But the show, which had seemed so original and fresh, is four episodes into its second season and has taken a regrettable turn. One of the sorriest TV clichés has just found its way into the drama: Amnesia.
