DD likes Clifford too, and Barbie movies, and Little Ponys, and Lars the Polar Bear (these ones are really cute) and Shrek, and Spirit and....

More educational, in the academic sense:

Microcosmos and Winged Migration, both from Jacques Perrin.

March of the Penguins

and last but not least:
Once upon a time ... Man

This last one I still have to get it in Spanish this summer. I am certain that DD will love it.
