It's a conceptual Sci-fi, about two engineers who invent a backwards running time machine in their garage. What happens next (yesterday?) is utterly original and also a bit confounding. The story unfolds for you, as it does for the characters, without any exposition and explores themes of want, power and friendship.

This film is also a masterful puzzle that doesn't easily lay out the answers. If you were confused by Memento, this is not for you. On the other hand, it's not purposely (irritatingly) confusing like Mulholland Drive. This is no acid trip, it just that paradoxes are a bitch.

Part of the enjoyment for me, was going online afterwards and reading some theories about the plot points.

10/10, with the caveat that this is a conceptual film, that won't wait for you to figure it out.
