There is not chance that this movie is intended to be in some kind of alternate time line.
Beg pardon? It's common knowledge by now that this is exactly what happens. Not only that, but it's an alternate timeline that *does not overwrite the original*.
Well, I have stayed too far away from spoilers I guess, other than watching the previews.
I have to say, setting this in an alternate time line is the stupidest thing I have ever heard, and I have been a defender this movie against criticisms with a wait and see it first attitude.
