I like the trailer but there are two things that bother me about it. I am attention to detail, if I see a flaw in a movie it bothers me and takes me out of the story. There are two things that the trailer does that is annoying. First, John Connor gets off a helicopter and shoots a T-800 endoskull. All I see is flash from the barrel and bullets not hitting the endoskull or the dirt. So that first part may be knit picking, but the second part is this: They open the Terminator guy up and realize that he is not human but infact a machine. I got the perfect remedy for this, I will use the butt of my rifle to knock out this Terminator so we can contact John Connor. Come on the soldier did not even hit him in the chip area either. How the hell are you going to knock out a Terminator?
Besides those two things, I do not like the idea of it taking place after Judgement Day. It was fun watching them run around in the past looking crazy. Also, do not look to deep in the Terminator timeline because if you did, John Connor should not exsist at all. They delayed Judgement Day and missed the opportunity to meet Kyle and send him back. If you think logically the chances of John meeting up with his father in the future is pretty rare since they postponed Judgement Day. John knows to look for him and also knows to stay out of certain cities but Kyle has no idea at all.
