Well, maybe its me, but I thought that the cases should have some kind of connection to reality. Like someone already have posted under allusions, there is no such thing as automatically receive a 4.0 grade point average when a roommate dies a violent death.
And who on this earth gets some kind of strange visions from sipping some absinthe? Has the writer even tasted absinthe? Absinthe is nothing else then ordinary alcohol (http://en.wikipedia.org/wiki/Absinthe)
But this episode does get a 1.0 score for the nice performance by Nelly Furtado, not that she was in the episode for many minutes(I think the absinthe spoon had more camera time).
I hope I dont have see another episode like this one or I will stop watch this CSI despite I like Mac Taylor more then Gil Grissom.
