Younger preschoolers will love this show and probably beg to watch it over and over -- it's colorful, the treasure hunt-like adventures are reasonably entertaining for that age group, and the repetitive "Look! We found it!" routine that Spyler and CeCe go through each time they find an object is lively and engaging. Parents, on the other hand, may feel like pulling their hair out after hearing that routine more than half a dozen times, and older toddlers and adults who've grown accustomed to the clever, highly interactive, and impossibly cute shows on channels like Noggin may quickly get bored with I Spy's simple games and subpar animation.
Still, the series encourages toddlers to be curious and use their imagination (Spyler and CeCe often come up with some creative solutions to their dilemmas), and it illustrates positive values such as friendship, teamwork, and sharing. I Spy is a wholesome show that gets back to the basics: simple animation, likable characters, and straightforward games that involve everyday objects -- and tickle the brain just enough to keep things fun and interesting.
