Screeners for Grimm went out months ago. Early screenings were held at Comic Con and were offered to Twitter fans. And of course, I kept putting off viewing my copy (hey, I've been busy). In the interim, I saw lots of (mostly Twitter) reviews that said the show was awful. So my expectations for the show were low, which may have skewed my opinion a little. But honestly, it wasn't awful.
Grimm focuses on police officer Nick Burkhardt. His dying aunt comes into town to tell him the truth about his heritage. He is one of the few remaining Grimms (as in descendants of the Brothers Grimm). The fairytales are real, the monsters from the tales exist in our world under thinly-veiled disguises, and Nick can see them for who they really are. Supporting cast includes Nick's partner, Hank; his live-in girlfriend Juliette; the police captain who is likely corrupt; and Eddie, a fairytale monster who is "reformed" from his life of terror. The acting is average at best.
So the premise is thin. See-through, even. I can get behind high-concept, and I am hoping that once we get past the lots-of-info-not-enough-airtime pilot, the concept will become secondary to the monster-procedural aspects of the series.
The monster aspects are pretty cool. They appear normal, but only Nick (or another Grimm) can see their true visage. The effect is twisty, creepy, and subtle. Grimm has the production values to pull it off. The fight scenes were well choreographed, and between Eddie and Sgt. Wu, there seems to be plenty of opportunity for sly humor. Executive producer David Greenwalt was an integral part in Buffy and Angel, and you can see that sensibility coming through.
So the verdict isn't in yet on Grimm. I'm going to give it a couple more episodes. If the monster action stays strong I think I can put up with the mediocre acting and flimsy premise. It's certainly no worse than this season's other fairytales-come-true show, ABC's Once Upon a Time.
