My kids got these for Christmas (ages 5, 9) and have been glued to the TV watching them. Enough action to keep them interested, and enough real world exposure, but nothing violent that I would object to. The values are great. Complicated enough to make them think beyond simple "rules" like don't steal. Makes them want to emulate good kids. We will get the whole series, for sure. I hope they make more.
This is a surprisingly excellent children's film series! The characters are believable, the action fast-paced, and most importantly these are truly Christian films. Unlike many films that merely mention God/faith etc, in passing, these films integrate and teach important aspects of the Christian faith. I highly recommend them.
