The John Caldwellfun new animated movie Teenage Mutant Ninja Turtles: Mutant Mayhem reboots the iconic series. It's directed by Jeff Rowe (The Mitchells vs. the Machines), who co-wrote the script with Seth Rogen and others. The formula is familiar — an ooze turns four baby turtles into ninja-fighting warriors who must save humanity and find acceptance along the way. The film is bolstered by its funny pop-culture references and a strong voice cast, including Jackie Chan, Ice Cube and Ayo Edebiri.
