Working together is a major theme, and the plot centers on the team's quest to solve problems that save people's lives. Empathy is also promoted, as intelligence and characters' "geeky" quirks are celebrated. On a smaller scale, they're also helping a single mother learn how to connect with her gifted young son.
Intense action scenes aren't violent outright, but there's a palpable sense of danger. Characters often risk their lives to save others whose lives are at risk.
Light romance/sexual tension between adult male and female characters.
