Deja vue. As a child in the 60s I read a Sci-Fi comic book (based on Ray Bradbury's short story of the same name) that had the characters traveling back in time and hunting dinosaurs from an elevated path. Since dinosaurs went extinct, killing them could be done without hurting the sequence of events that brought us to where we are today. During one expedition a member of the team stepped off the path and killed a butterfly. Because that species did not go extinct and was a pollinator of other plant species, the sequence of events was broken. This started a chain of events that changed the entire course of the world, and mankind's, history. Plants were not pollinated, generations of evolution were lost, forests that should have been weren't. I've never forgotten that first experience with what was termed chaos theory and the youthful realization of the fragility of our timeline. In fact, that comic book was the last moldy one I threw out some 20 years ago. I remember reading it one last time before it went into the bag. This movie brings that basic story to the screen with some wonderful enhancements. While I could debate the obvious flaws in the story, it is still compelling to those that would choose to understand what we call time. I would say that time and space cannot be separated and that backward time travel includes the space of the entire universe. Undoing the movement of the entire universe is inconceivable. This is why some choose to play with multi-verses and all timelines existing simultaneously. But it is wonderful that man can even conceive of time-space and what could be.
