The downsides are Dominic Monaghan, a serious miscast and way out of his depth, and the slipping between subtitled Swedish and un-subtitled English which, at times, is barely audible. The upside is a seriously involving mystery about serial killings set against some wonderful Swedish backdrops. It may not be the best detective story you'll ever see but it beats the pants off of most TV fodder these days. And, aside from Mr Monaghan, the acting is excellent across the board with plenty of sub-plot action for those who like such things.
Worth a viewing of at least the first two episodes to let it suck you in, which it will do in spades full.
