Well, fear not Turtles fans, for Bay has taken to the forums on his official site Shoot for the Edit to issue the following ‘reassurance':
“Fans need to take a breath, and chill. They have not read the script. Our team is working closely with one of the original creators of Ninja Turtles to help expand and give a more complex back story. Relax, we are including everything that made you become fans in the first place. We are just building a richer world.“
So there you have it. No need to worry, Bay has it all in hand. Just like he did with The Transformers.
