Claire has watched Arthur for months now. This show does not get old. There are so many characters and so many episodes (hundreds!). As I write this, the show is in its 14th season, so it has more legs than something like Imagination Movers, which Claire tired of once it started repeating its limited episodes a lot.
The show is also engrossing. It has stories that a kid Claire’s age can relate to, involving friends and fun, plus conflicts and insecurities and how to deal with them. I feel like she learns positive behavior from the show. Even about.com has a lot of good things to say about the show.
