While every episode of the show is about law enforcement officials using science and creativity to solve crimes and stop criminals, the series' relentlessly dark, violent tone overshadows positive take-aways. Repeated focus on violence against women.
Very bloody and gruesome. Lots of graphic inside-the-body shots. Many dead bodies. Occasional episodes feature the CSI crew in peril.
Varies from episode to episode; some installments have focused on sadomasochism, infantilism, etc. Some romance between characters, though very little explicit sexual content.
Occasional swearing -- "ass," "bitch," etc.
Product placement occurs subtly, mostly with cars and technology.
Drinking, Drugs & Smoking
Relatively minor alcohol use by main characters. Drugs often play a role in crimes.
