Well, suffice to say this wasn't well received.
Now, Bay has responded to the fans on the forums on his official site with the following:
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.
The new Teenage Mutant Ninja Turtles movie is slated for a Christmas Day 2013 release.
