What I find most incredible is how utterly wrong the tone is. TMNT has always had a lighthearted touch. The turtles are just teenagers and they like screwing around with each other. They fight ninjas because that's what ninjas do. Their origin story is a goofy accident, and they're only ninjas because their caretaker was a dojo sensei and that's all he knows.
Now they're bio-engineered purpose built heroes or something, and Shredder is going to be some CEO of bio-engineer hero corp. Oh, and there is a military vehicle in there, because Michael Bay is BFFs with the Army.
I guess it's possible the trailer is deceptive. I'm guessing the original TMNT trailer didn't talk much about the Casey/April love subplot and Leo finding his way and everything. But this is Michael Bay and I have low expectations.
