This dated movie is best for diehard TMNT fans only. It was inevitable a live-action Mutant Ninja Turtles Movie would be made, with actors in suits. The abundant martial arts violence caused some controversy at the time (in Britain this "family film" was actually censored from children), and in the era before Crouching Tiger, Hidden Dragon, critics pretty much condemned all kung-fu movies, from Bruce Lee to Jackie Chan, as R-rated bloodbaths. Just the idea of a kids' karate film raised doubts (though the Karate Kid movies were allowed to get away with it, go figure). Teenage Mutant Ninja Turtle movies made the fighting reptiles more comical and slapstick action-heroes, tossing off wisecracks and never drawing blood despite their swords and daggers. However, an aura of menace and brutality settles over the film when it's human against human, especially the wolf-packs of boys vs. April and Casey Jones.
There's something of Pleasure Island in Pinocchio about the way the movie makes the street-gang lifestyle of the Foot Clan seem appealing; a cool secret headquarters filled with skateboarding, video games, music, girls, cigarettes, and brotherhood. Even though it's supposed to be a big lie, the impression is still like a recruiting poster. Splinter the Rat, on the other hand is by far the most noble character here. He's really such a Yoda-like standout paragon of wisdom and kindness you wish the movie were more about him. Rats never had such good PR. Love them, hate them, the Mutant Ninja Turtles opened the floodgates for kid-friendly martial arts flicks in the English-speaking world, and the subsequent Three Ninjas series was pretty much Turtle schtick with teenage non-mutant ninja humans. Imagine that.
