Doug: With a great opening theme song, lots of heart, and plenty of laughs, this light-hearted cartoon on Nickelodeon helped kids navigate the awkwardness of adolescence, reminding them they aren’t alone. It waded into several issues kids have to deal with, like friendships, being an underdog, dealing with bullying, and having an epic crush. Thankfully, despite all that, it also knew how to not take itself too seriously and maintain a light tone. The main character’s name is Doug Funnie, after all.
