A movie with a silly snowman AND the word "gassy?" My 5 year old son loves it!
Though my 11 year old son acts too cool for it, I think he's just tired of hearing the songs over and over. He did watch the entire movie for a second time when we watched it recently though, so I don't think he hates it.
We act out Frozen all the time here - the 8 year old girl is always Elsa, I'm Anna, and the 5 year old boy is Olaf. Though as I type this, the 5 and 8 year old are both belting out Let it Go.
