See it if you're looking for theater for your very little one. My 2yo was totally hooked and loved putting his paper fish in the paper river on stage.
Don't see it if you want more of "story" for your kid's entertainment, or more singing, dancing, spectacle. This had a more European, clowning sensibility.
See it if you would like to watch sg out of the usual, or you just want to relax and have fun.
Don't see it if you want a straight storyline.
