Pitched as a cross between Skins and Heroes, it's about a bunch of young offenders on probation who get caught up in a storm and start developing superpowers afterwards. They're all spectacularly obnoxious, but in a variety of different ways and entertainingly so, which makes for a fun new spin on the whole superhero idea. They're on probation, for a start, so they're already criminals; criminals with superpowers!
Best character of the lot being Nathan, who spends most of the first season - six episodes, in common with most British season lengths - wondering what his power is and being an outstanding asshole to everybody and still being brilliant.
It's refreshingly confident in it's own premise, and it's got a nice mixture of cheeky British humour and a genuinely grim sense of menace running right through it. I've loved every bit of it I've seen so far. You guys probably can't watch it on E4's online player, but I'm sure it's out there on torrents and it's well worth seeking out. The DVD is dirt cheap too, but probably has a load of music changes; the last episode had, hands down, my favourite use of Lady Gaga ever, and a scene where somebody saves the day in part thanks to Smack My Bitch Up, so it would be a shame to lose out.
