Having presumably arisen from an NBC executives meeting where one of the big cheeses said: "We can never have too many cop shows, and all of that monsters and goblin shit is really popular at the moment. Give me cops and monsters, people! And a large skinny latte." This is Grimm. Although at times it's also a bit grim. So at least if you tuned in accidentally expecting grim-ness you wouldn't be too disappointed.  

Having realised they hadn't ebay-ed all the prosthetic make-up and strange swords from Buffy, the makers of Buffy bring us a new bit of running around in prosthetics with strange swords, as well as a similarly styled and paced bit of moderately scary drama with the occasional moment of humour. Grimm is based on the premise that rather than being fairytales, the 19th century stories were actually factual accounts. Before you get all excited and head off to find the ginger bread house and knock up a spot of porridge for Goldilocks, remember these are mostly dark tales. So in this universe, the Grimms are hunters, not book writers, who have passed down from generation to generation the task of keeping the world safe from monsters.

Nick Burckhardt (David Giuntoli) is a modern day Grimm who helpfully is also a homicide detective. Helpfully, because that means he can get on with all that saving the world from monsters in work time and keep his evenings and weekends free. He has only recently discovered his skill for spotting the monsters kicking around and so is having some adjustment issues. In the same way you might feel if you realised Winnie the Pooh was not only real, but skipping about the woods holding hands with Piglet on a day to day basis.

Faced with the reality that monsters are roaming the streets being, well, monsters, Nick finds himself having to keep up close and personal with them in order to stop them murdering and pillaging the streets. Thankfully reformed Grimm creature Monroe (Silas Weir Mitchell) reluctantly offers to help Nick out: "I used to be a big bad wolf - but I'm done with the bad thing."

So if crime-fighting, monster-ing and watching people run around with swords are your bag you're in luck as this is a pretty decent example of all the above. Plus, presumably, later in the series you might be able to see a man try and blow a brick house down. Which, let's face it, is the most extreme display of strength you'll see outside a World's Strongest Man contest this side of Easter.
