Dark comedies thrive when mixed with two genres; crime and family drama. Dark rom-coms also can work but Riff Raff is all about family and the trouble we get into jus by being a family. With one hell of a cast and the director of the fantastic Guide to Recognising Your Saints, Dito Montiel, a director that knows how to paint crime and family together on screen, you would think everything falls into place. Though the darkness is most certainly present, the comedy is just not.
