Avis Metacritic

Exceptionally well-made family entertainment, this 3 Ninjas is constantly inventive, action-filled and funny, with a flourish of good special effects.

The incredible silliness doesn’t quite erase the bad taste of this kid’s movie featuring an implied dozen civilian casualties, but it helps.

Pathetic yet stupidly entertaining for several minutes of its interminable running time, 3 Ninjas: High Noon at Mega Mountain makes half its cast look like retreads and half like fresh ponies desperately karate-kicking a dud script to see if it has any signs of life.

For most moviegoers over 12, this, the fourth Three Ninjas movie, will be interminably boring. But it's possible that young children will enjoy the film, since it falls into both the action category and the children-are-smart-adults-can't-do-anything-right genre.

As the fourth entry of a painfully uninspired series, this version features new actors portraying the trio of adolescent warriors. [10 Apr 1998, p.49]

Only small children with limited attention spans will be impressed by the lackluster kung-foolishness in 3 Ninjas: High Noon at Mega Mountain.

The best you can say is that it's all pretty harmless and pretty stupid.
