We recommend How To Train Your Dragon 2!
We had a great time screening How To Train Your Dragon 2 at our Dragon Party Family Movie Night! We created a massive dragon to hang as a decoration and tucked into this awesome party pack from Fox. You can see our project here: https://encinomom.wordpress.com/2014/11/06/dragon-party/ We were inspired by the installation by Chinese Artist Ai Weiwei from our recent trip to Alcatraz.
You can try this at your house. It would be a fun way to celebrate Chinese New Year, too.
