It’s been far too long since the Teenage Mutant Ninja Turtles was fun. The concept of four anthropomorphic turtle brothers trained in ninjutsu is inherently goofy — something that recent iterations of the pizza-loving vigilantes forgot in a bid to compete with every other grim-dark franchise. These are characters whose catchphrase is “Cowabunga!” and whose heightened antics felt totally at home with the “radical!” spirit of the ‘90s. So thankfully, Teenage Mutant Ninja Turtles: Mutant Mayhem brings that radical goofiness back with a propulsive, vibrant animated flick that transforms franchise nostalgia into something invigoratingly new.
