The show portrays doctoring as a tough business that brings up difficult ethical dilemmas, and the takeaways are rarely black and white. That said, the doctors often act heroically to save lives. Themes include compassion and empathy. Many storylines also promote awareness of conditions like Alzheimer's, etc.
Scenes aren't always graphic, but are occasionally gory and can involve surgeries, blood, critical injuries, and even death. Some episodes deal with shootings, explosions and other violent incidents.
The show puts a lot of emphasis on the characters' personal relationships, most of which are sexual in nature. There's plenty of bed-hopping between co-workers, including some same-sex pairings. While the characters kiss, embrace, and have implied sex, no sensitive body parts are shown.
Some language of the "ass" and "damn" variety.
Drinking, Drugs & Smoking
Characters meet regularly at a local bar to de-stress after work. One character uses alcohol to the point that it negatively impacts his career, and he's temporarily suspended. But he eventually goes through rehab and makes positive changes.
