I am so enamored with this kind of film. How many people have asked the question after having an accident or chanced upon something, "If I had only left a minute later, none of this would have happened." Now we get into the who time continuum thing and parallel universes. I know this isn't a science fiction film, although a Twilight Zone episode may have fun with this plot. When we are dealing with the characters colliding through the fourth dimension, a whole different set of circumstances are put in motion. The reason we can never travel back in time (while forward is possible) is that time would then become mutable and what we are may no longer be and then we wouldn't travel back in time. Two roads diverge in a woods paraphrasing Robert Frost, but what if we could take each of those roads and see what happens. This movie is quite magical and does the best it can to get Gwyneth Paltrow through her parallel universes and see the things that one would see. I think the problem is that unless we get into quantum physics, it's hard for the average person to really reconcile these sorts of events. I thought the acting was very good and believe things as they unfurled. I would recommend this film if you like to think about the possibilities it envisions. Try it on yourself sometime and extrapolate your own existence from some fork in the road and imagine what may have been.
