"[52] Common Sense Media also praised the free movies' video quality and topic variety, and writing, "The videos cover a lot of ground but are easy to follow and fun to watch; they'll explain things slowly and deliberately and at a level that's appropriate for young elementary school kids [but] it will be largely up to parents to get kids engaged in further exploration of the material.
