I suppose I question things I shouldn't, like that guy jumping off a building to stop himself from running that women over in the future, couldn't he just move to the North Pole? 
Yeah but the thing is he doesn't see where he runs her over does he? For all he knows he might move to the north pole go for supplies in his snow mobile and run her over haha. But thats the premise.
I suppose he could of just stayed in his house for 6 months but then how does he pay the rent. Its deep man. haha
But i think the idea was for him to show everyone that nothing is set in stone.
Like i say the premise is good but they haven't really delivered for me yet. When you compare it to Fringe for example its just dithering along without progressing the story much.
My fear is that to boost ratings they will have another Flash Forward and then another and then it'll get hard to keep up. For me if they have more than one Flash Forward then it should be capped at one a season.
