"Alright so the main character is a cyborg named Marcus. For some background, Marcus was a criminal who was executed in 2003.
He donated his body to Project Angel which was involved with SkyNet. They take his body and make a terminator out of him so he's a terminator skeleton but has living muscle/skin and a beating heart too. At the end of the movie John Connor is fighting a T800 model 101 and loses. He dies and the top resistance people come up with a plan to help the resistance keep fighting on. The resistance feels that it's important to keep the image or idea that John Connor is still alive so the resistance keeps going. So they rip off Marcus' skin and put John Connor's on the skeleton so now Marcus is John Connor."

Remember I was saying before that my only concern was that I was afraid the creators might try to be too clever with the whole thing (I thought it would be with some crazy time thing) but alas its something like this    In my mind the whole idea of John Connor is that he is yes mean't to be a great leader and warrior but also he's mean't to be simply HUMAN aswell!!
If this is true we would have the ludicrous situation where the humans will be fighting the robots while being led by a robot  
Why can't we just get a great future war film
