I love Max and Ruby, but I'm assuming Rosemary Wells didn't have a lot of involvement with this adaptation of an episode of the animated series. I enjoy the show, but the voices, music, and motion are what make it so cute. This book version is just flat and bland, and the original episode isn't one of the stand-outs from the series either.
It doesn't help that this story is one of the more formulaic ones from the show, where Ruby is trying to accomplish something, and it seems Max is always interfering, but in the end he saves the day just when it seems Ruby will fail. In this one specifically, she is assembling a complete album of leaves from different tree species in the neighborhood while Max is moving all the fallen leaves around chaotically.
