Thanks for the explanation. I don't know, it's not that I find it unrealistic (I don't) but I find it not appealing to me.

I am pretty shallow so if, perhaps, they cast someone I find more appealing as Four, I would have still checked it out and been more excited for it despite my story misgiving but as it is, it's not a draw so...

Who knows, I may love it anyway.

Do they ever explain how she time-traveled? Because it seems odd if not - i.e. what happened to the person in the past she displaced? I can't help but think she hallucinated the whole thing in a coma or something.
