For a kiddie flick, and this film is certainly not aimed at anyone upwards of adolescence, '3 Ninjas' isn't bad in the grand scheme of things. It is, undoubtedly, better than many of the martial arts films aimed at children that have been produced (check out tosh like 'Tiger Heart' and 'Double Dragon' for proof!).
The film centres on three young brothers-- thirteen-year-old Rocky, twelve-year-old Colt and eight-year-old Tum-tum-- who have been studying martial arts since they were toddlers, under the tutelage of their sensei grandfather. The boys' father, an FBI agent, doesn't approve but he is too pre-occupied with catching bad guys to stop them. Then the boys find themselves at the centre of a kidnapping plot by one of their father's perps Snyder, who incidentally was also trained in martial arts by their grandfather.
The film has many unrealistic scenes where the three wee moppets take down hordes of grown men with ease and cue the 'Home Alone' style tricks as the boys rig their house against three would-be teenage kidnappers who have the IQ of toast (one of whom was portrayed by Patrick Labyorteaux, who went on to play Bud in 'JAG'). However, to the film's credit, Snyder was depicted to be genuinely cruel and threatening and the three young actors, especially the elder two, who played the brothers were not as irritating as many child actors can be.
This is an enjoyable film for kids, especially those interested in martial arts (it did influence me to take up Tae-Kwon Do as a kid!), or those who watched it as a child themselves. Unfortunately, the two sequels '3 Ninjas Kick Back' and '3 Ninjas Knuckle Up' were much cheesier and less watchable and the fourth film '3 Ninjas: High Noon at Mega Mountain', filmed much later in 1998 and featuring different kids in the role of the brothers, was just so atrocious that it's better to pretend it doesn't exist.
