the gone dead train

Has CSI turned into a horror show? I haven't watched the show in quite some time, but the opening of last night's episode, "The Gone Dead Train," was like a classic Hammer horror flick: a coroner works on the body of a person who died mysteriously (very gross), there's an ominous rainstorm at night as Catherine goes to the apartment of a woman, and then in the dark the woman attacks her for no reason (tied to an illness that's affecting people - swine flu?). There's even a scene where Catherine rips down the drapes, a la Peter Cushing in Horrors of Dracula, as if she could force sunlight on the woman and make her turn to dust. Here's the episode if you missed it.
