Honestly, there would be more impact of the machine wasn't in the background and the toy wasn't a teddy bear. If there was like a backdrop and some Ninja Turtle toys, and there was more of a story going on other than "owo what's this", you'd be compelling.
Like the Ninja Turtles are chasing something we don't see, building up the anticipation, and going through a cardboard scene after scene. Then having them confronting Shredder at the end, showing their revile at what he's done, only to have it reveal that he was leading them to a trap and underneath was the shredder. Finally wrapping up, showing their anguish and death, and the postmortem scrap that was left, would I feel this be more amazing of a thread than presented now.
