This episode gives a really good look into the mind of Det. Goren. Nicole Wallace has to be the best adversary he's faced and the two play so well off of each other.
Vincent d'Onofrio does a superb job of showing the frustration of dealing with someone like Nicole. You can practically feel it coming from the set. It's good to see the human side of these people and not just dry detective work. The one flaw (and it sticks out like a sore thumb) is that one of the characters refers to "the virus". Anthrax is caused by a bacterium, not a virus.
