Parents need to know that this informative documentary series is great for curious viewers of all ages who like to know how things work. Detailed investigation and narration is enhanced by illustrative computer-generated images to explain which tools professionals use to perform their jobs efficiently. Some of the featured professions are associated with violence -- law enforcement, firefighting, etc. -- and although no one is ever shown injured, scenes of house fires or SWAT teams swarming may be frightening to the littlest viewers.
Positive messages:The series offers an intriguing, educational look at how high-tech tools help in many different jobs.
Violence & scariness:Depending on the featured trade, men and women are sometimes shown in life-threatening situations (like firefighters putting out blazes), but no one is ever injured. In an episode about SWAT teams, members carried guns.
