My initial response to this series was that I kind of hated it. However, my almost ten-year-old son positively loved it, so I started paying closer attention to it. I'd say it's geared toward tweens and older. After giving it a fair chance, I discovered the writing is actually quite intelligent, and the humor causes my son to watch them over and over... and over. In just days, he's started weaving information about Marie Curie, Queen Elizabeth I, and others into conversation and speaking intelligently about them. These are people of which he previously knew little or nothing. This show won't be for everyone because of its quirky nature, but I personally hope they continue for many seasons.
