Just when you think cookie-cutter cartoon series have become the norm, out of nowhere comes this slightly irreverent comedy. Gravity Falls is about two fish-out-of-water visitors to an off-the-beaten-path burg that's brimming with small-town secrets and unusual characters. Although Dipper and Mabel take very different views of the nature of their adventures and often have differing opinions about how to proceed, when push comes to shove, their sibling bond makes them a formidable team in the face of whatever this bizarre town throws their way.

As far as the show's content goes, there's not much to worry about, but in many ways, this series is better suited for slightly older audience members who will pick up on the subtleties of the clever Simpsons-esque writing and characterizations that will go unnoticed by youngsters. What's more, there are some tense moments during monster encounters and other mysteries that may frighten kids who are sensitive to that kind of scare.
