The turtles face a new challenge when Shredder escapes from custody and joined forces with mad scientist Baxter Stockman and henchmen Bebop and Rocksteady to take over the world.
It's empty-headed nonsense, of course, but the action has a rowdy vigour and the turtles' boisterous high spirits will strike a chord with younger viewers.
Goofy where the previous installment was gritty, and graceful where the previous installment was chaotic, this sequel is such a huge step in the right direction that it may be more accurate to think of it as a mulligan.
Thankfully funnier and less serious than its predecessor, Teenage Mutant Ninja Turtles 2: Out of the Shadows is still juvenile and simplistic storytelling.
