I'v read on a few sites, where it's commented that Kyle Reese befriending the Cyborg Marcus seems a bit out of character. I just wanted to note that I think this article is very spoilerish, concidering that the information given in the article about the film is new info about the film. Remember, Marcus was supposed to have a *big secret* that's to be revealed during a twist ending. It could be that Marcus turning out to be a cyborg is the twist (With the way they've talked about the *twist*, how can anyone have not predicted this?). Perhaps Reese's hatred for the Terminators is because of Marcus and his role in this new trilogy??? Maybe, young Reese didn't know that Marcus was a machine...
I also want to add that I like the idea of the son being in his 30's and the father in his teens. F-ed up!
