Grimm is one of the best shows I've watched in the last 61 years. Really!
The makers of this show have given us something very different and tremendously entertaining right from Season 1,episode 1 to Quills, the third show of this second season. The premise, that the Grimms have been after these creatures (that we all thought were imaginary) for centuries, is terrific and they have peopled the show with a fascinating main cast with really fine actors.
How great to have an entire group of people(?) that you can engage with and wonder about; their lives, backgrounds and loyalties. The Chief-of-Police is fascinating and mysterious. I am fond of Monroe, the big, bad wolf, or Blutbad, but have enjoyed the entire panoply of wonderful fairy-tale creatures.
I highly recommend that, if you're not already watching, you tune in and watch, and (like me) buy it; you'll want to watch these shows again.
