I have saw first part of this series and it was fantastic and this is greater than it.Shredder is run out from jail and he meet to an aliens leader while transportation. The Commander gives him a purple portion which transport mutants into humen and humens into mutants. He mutated two person in rhino and another one in big pig. They all go to find out the parts of a machine which opens the portel for coming war ship of alien Commander. During that period fabulous action, comedy and drama is happened and it is fantastic. After founding portel he open the portal. When battleship started to making from small parts. Turtles come out from chembar and fight with commander and save the world. I like the animation and story creation. Sound quality and choreography is also too good. Totally in short movie is fabulous.
