The oversized terrapins are characteristically flip as they backflip through an unnecessarily muddled plot.
Less amateurish than the 1990 original, less embarrassing than the 1991 sequel (with its mind-boggling Vanilla Ice ninja-rap number), this may be the easiest installment in the series for parents to sit through.
New York Times:
The Turtles themselves are better-natured than ever, and even nicely mellowed.
The first film was bad, the second worse, and the third almost unbearable.
The wisecracks have been cut back, and where once the Ninjas' dude-speak was original (influencing, for example, Wayne's World) it's now merely imitative.
If the first sequel was a photocopy of the original, this second sequel is a tracing of a photocopy. It's the same business twice removed, and twice diminished.
