The other commenter was correct in saying that it's not a show for the kiddies, and yes, I don't know how PBS managed to broadcast it without the FCC stomping their heads in, but it's a fantastic show, so hurrah for them!
And as for the comparison to "Prime Suspect," it's apples and oranges. "Touching Evil" is more stylized and less procedural. The title is apt, as its focus is less on the evil itself or the process of combating it, and more on the damage it does to those who touch and are touched by it. The protagonists grow harder, more detached, more despairing, and more absorbed by the horrors their occupation revolves around, and the grief of the victims is almost palpable.
If it suffers from the occasional bout of unrealism, I didn't notice. I was too absorbed by the atmosphere and the pathos. It's superbly done and well worth watching. The acting is stupendous, the characters intriguing, and the production brilliant. It's one of the finest crime dramas I've ever seen.
