If you liked Kindergarten Cop, there's a good chance you'll like this film. It's in a similar vein, the plot of the hardened male (Vin Deisel) forced to deal with multiple children. But this movie could've been better. I thought a lot of the action scenes seemed forced and a little on the ridiculous side. I love ninjas, but they just weren't well-played. But the side-plots involving the children's school were mostly entertaining, Morgan York (Lulu) stole the show, and Brad Garret (Vice Principal Murney) was hysterical. Scott Thompson (the Director) was also quite funny, but I would've liked to see more of him. So though I found the action portions disappointing, your kids would probably like the movie and you won't be too tortured.
