This is a kids movie. Do not watch it if you are older than the age of ten. I saw this film when i was seven and i loved it. So by all means rent it for the kids but it probably would not entertain any other age group. I used to love all these ninja movies when i was a kid. It is just something about kids kicking butt that makes a child feel empowered. I even used to have a sega genesis like the youngest surf ninja. This is a spin off of the three ninjas movies, which i absolutely used to love. If you have kids and you want to rent them some movies you should get them the three ninja movies first and then maybe surf ninjas.
