A self obsessed and insufferable little man repeatedly does the bare minimum of his job, and every time someone is hurt or killed the only thing that matters is how it makes him feel. If the deeply flawed protagonist was the angle they were going for then fair enough, but everyone around him talks as if he's the best detective they've ever seen, while cleaning up his mess and dealing with his tantrums (he repeatedly stomps out of the room like a five year old).
Also half the positive reviews seem to think this page is about the swedish version.
