Brighton-based Spy Monkey are theatrical loons who delight audiences with their pure ridiculousness.

Their first production, Cooped, was a spoof Hammer horror comedy which reduced me to a giggly, teary mess.

I raved about Cooped for months and maybe my own hype resulted in my slight disappointment with Stiff. The characters were less fascinating and the plot lacked the ingenuity of Cooped.

The first half-hour dragged a little but the final 30 minutes recaptured the magic that made Cooped such a work of genius.
