My now 4 year old has been hooked on Stella and Sam for over a year now. He identifies with Sam (must be the hair!) and loves the idea of going on adventures. What I like most is that the episodes are so focused on imaginative play and getting kids outside, two things that I think preschoolers need more and more as we become a technologically-driven society. Here's to the cardboard boxes that make great forts and spaceships!
