The BEST thing people can do (we can only wish) if we want to see an end put to these bastardizations of movies is to speak with their wallets and don't see the movie in theaters. The studios (quite evident from other crap films out) just don't listen to our opinions. What they do listen to is money. If people wanted this crap to stop they just have to hit them where it hurts which is box office sales. That's when the execs get together and say, "Gee, what happened there?" Then they'll evaluate and see why people didn't want to see it, what was wrong, get rid of the people behind it and draw up something the people want to see.
It's all about $$$$$$ and not a good story, at least with most films. Sacrifice of more mature ratings at the benefit of more ticket sales, but less integrity of story source material, more explosions gain more interest, sexual innuendos gain the teenager audience, or whatever it is... The mentality first and foremost should be the quality of the film and can that make them money. If not, then do something else.
I'm sorry, but i've never been so fired up upset over a movie reboot like this. As a huge TMNT fan I am just beside myself right now how such a big studio with so much money, source material, gazillions of pieces of concept art, great characters, and stories that they could manage to screw up just about every aspect of that in what I have seen so far. They threw the Ninja Turtles into a Mission Impossible film and it looks so disjointed and non-TMNT it's just atrocious and embarrassing.
