Supernatural: Bad Day At Black Rock

Sam and Dean are called to break-in at a lock-up in Black Rock that was owned by their father.

Their investigation leads them, and the audience, into a fascinating look at life in their world.

Even just the detail in the lock-up is incredible, with its store of weaponry and various hocus-pocus trinkets and artifacts.

The Winchester's cross paths with Bela (Lauren Cohan), this episode's obligatory hot babe - a woman who knows The Truth about the world but instead of becoming a hunter "acquires unique items for select individuals" (for large sums of money) - and a zealous hunter, Kubrick (Michael Massee), put on Sam's trail by the imprisoned Gordon Walker (Sterling K Brown) and convinced that Sam is the embodiment of evil.

A couple of useless punks have stolen a sealed box from the lock-up and inside they find a rabbit's foot - little realising that it's cursed. Whoever handles it gains incredible luck until they lose it (and everybody does) at which time their luck turns bad and eventually fatal.

This leads to numerous very entertaining and comedic moments when people's luck becomes unbelievably great (e.g. Dean throwing a pen and lodging it in the barrel of an antagonist's gun) and one particularly gruesome moment when one of the hoods trips backwards onto a large kitchen fork - which pops out of his mouth. If nothing else, this season of Supernatural has been the most bloody!

With the rabbit's foot there simply as a MacGuffin, Bad Day At Black Rock almost suffers from a surfeit of great characters, making return appearances from Kubrick, Walker and Bela pretty much obligatory as there is still so much of their stories to tell.
