OK, movies about time travel, there are enough also one must not make a lot of thinking about the Logic in the context of encounters alter ego in different timelines. But as this substance has been implemented here, deserves conserve quite a WOW effect! There is not many of these small precious gems ala arthouse cinema. Leaving aside the "reality" times before the outside, so I have rarely seen such a clever thought-out script. There Is it really only due to a sci-fi movie, but rather a tragic drama in light sci-fi look. One can not write about the action, without taking up the appeal of the film in advance, only this: It is about time travel and the irreversible fate lines and paradoxical encounters with the "alter ego". As a filmmaker I can confidently confirm that I am not the implementation of the substance about time travel in this form as yet have seen this film has little action, but survived by his uncanny exciting narrative.
One can only congratulate Spierig brothers for their sense of such sophisticated in scene set materials. However, you can save the 3D version, because you might as well press the 3D button on the remote, has the same effect. What is he thinking, I do not know, because the film has such an "appreciation" not really necessary!
Finally, one can note: not a film for the brain-from-mainstream audiences, everyone else should fine this small contribution from Australia more than a chance to give, because they will be rewarded by a good arthouse Cinebeitrag!
