The latest trailer for the Michael Bay-produced Teenage Mutant Ninja Turtles is here, and it effectively raises the bar on the action seen in the last spot. Here, the turtles show off their best moves — and we all get to take a good look at Shredder. Buzz is already ramping up surrounding the movie, though fans may worry about the quality of the final product. For one, an early photo of Shredder made him look a bit more like a Transformer than TMNT fans may remember, though that's hardly a reason to believe that there won't be plenty of ninja action to love.
