I don't mean the episode was disgusting as a whole, or disgusting meaning the episode was bad, but the villain is perhaps the most evil villain this show has produced in its 5 seasons. The way he was evil made me cringe the entire episode and I just can't fathom how anyone could do that to people, or how anyone could survive it.
This isn't your typical Cold Case episode, from a structure point of view. We know who the criminal is from the very beginning. I would say this episode is closer to the Without a Trace structure than Cold Case.
It's not a bad episode. It's just one that is hard to watch and really makes you think. I don't think I could watch it again.
