We are looking forward to taking our son to see this movie. And by extension, our daughter who will be really too young to care.
However, my son saw the trailer for this movie before Toy Story 3 but he didn't notice it until the latest Tinkerbell movie.
I don't think I have seen my son react so positively towards something like he did for this trailer.
He LOVES Flynn Rider. He has memorized the lines Rider says in that trailer and he even will do the "Smoldering" look to try to get his way or, for the most part, get a laugh.
Whether this is a true "Princess" movie or a "Princess" movie from the princes POV remains to be seen. But, Disney has done a good job at hooking my four year old son who wants nothing to do with Princesses.
