It's never surprising to me to see a modern television show, with all its secular writers, give credence to the occult. They certainly don't that to the opposite: Christianity. That's been scoffed at a few times by Bill Petersen's "Grissom" in this show. To be fair, he admits to going to a psychic once but generally isn't a believer in that, either.
The "believers" are everyone else, especially CSI field man "Greg Sanders," who pushes it when he can here. So does a police captain, who claims the psychic who was killed in this show gave him evidence on a past case that no else did. It's all treated with credibility. Thank goodness, "Grissom," after the case has been solved, does fit things into the right places when he explains the problems people have with "perceptions."
In all, no matter how one views "psychics," it wasn't all that great a show and didn't have any suspense to it. However, like almost all CSI episodes, it didn't bore me.
