True to say, it is a powerful movie. However, none of this ever happened because a time machine was never BUILT for this to happen! Love and romance mask the movie and make you believe that parallel existence is possible but in reality does not deliver the truth of multiple dimensions. And in our stage in life, the mind has not adequently matured to truly visit different planes of existence. And in the end, it makes no difference because it leaves you hanging to find out when and where the characters of the story were and if it really happened. One should visit a movie called "Another Earth" with a similiar concept but more focused on a possible reality. This movie focused way too much on rivalry between Jamie and iIsaac, the main characters. Although, it's not too bad.
