The mothership of the CSI franchise is the only of the CSI shows that are watchable, Miami and NY are just terrible in comparison. But with that said the main CSI is kind of unrealistic in the involvement the Crime Scene Unit does in solving crimes. The way the show makes it out to be it's the CSI team that solves the cases with the assistance of an occasional detective when it's really the other way around. It's the detectives who solve the cases with the assistance of the CSI's, not the other way around. You don't see real CSI's interrogating suspects or questioning witnesses. The CSI's jobs is to find finger prints, DNA and all of the science part of the investigation. CSI's don't go on raids and they definitely don't carry weapons.
