Series Two has some excellent cinematography, placing grim housing estates against a timeless Welsh landscape. The use of Gaelic, too, gives the viewer a feeling that they're observing a foreign world (and I'm from the UK!). Series One, however, is burdened with a clichéd script, and is stretched out far too long. Rather than the seductive bleakness of Scandi-Noir, there's an atmosphere of unappealing drearyness. Series Two proceeds the same way (I was prepared to give up!), then makes a remarkable turnaround near the end. The conclusion presents a chillingly accurate depiction of a sociopathic youth. There's also a genuine sense of pathos and tragedy - in the way that deprived neighbourhoods can breed this criminal type, and in the devastating effects of their behaviour on the immediate community.
