Here are some other great mystery adventure shows for kids and/or teens:

ABSOLUTELY !!! the best way to know if a kid movie is good or not is by surveying kids or have them rate it !!!
The Perfect Game, and Facing the Giants
camp rock 2 the final jam IS THE BEST
For me it is good as most fantasy movies are for kids, it helps develop the imagination and creativity of children.
