Parents need to know that this documentary series presents evidence and supposition from all sides of some of history's most intriguing mysteries. Expert testimony combines with eyewitness accounts, video footage, and dramatic re-enactments to present various plausible answers to age-old queries. There's very little content that will raise eyebrows here other than a little violence (mostly implied) in war scenes, but the mysterious subject matter and dramatized scenes (though vague) may upset some kids.
Positive messages:The show offers an educational look at the scientific process of solving mysteries.
Violence:Some re-enactments of historical mysteries may include battles (with men carrying guns) or crashes, but injuries are usually implied rather than shown.
