The only thing I didn't get.. Spoilers abound
Well, that's not exactly true, there's two things that are bugging me. The first is the whole "not being able to go outside becuz we've been touched by the man from the future.." That's never explained and it just seems like a big gaping plot hole...
But mainly my question is this: I get that the guy coming back was the son from the future, and that the mother went back with him, obviously they treated her wounds (and maybe did other things to her, as others have pointed out she did seem kinda different..) but anyways, since she teleported back does that mean that she's going to flicker in and out like the other dude? Or is she back for good?
Another thought- Even though they make it seem like the guy doesn't recognize his own family til the end, that's apparently not true. He told them to run at one point early in the movie, perhaps because he realized that as the experiment went on he would end up completely losing it and hurting them. Plus that dialogue from the little girl early on when she's talking to him alone, she says "she doesn't think you're you" (referencing the mother)or something to that effect, so she must have known he was her brother.
Far from the best movie I've ever seen, but I certainly liked it better then most of the posters on this board lol. 5.5/10
