The reason I'm not a Sci-Fi aficionado is that they're rarely this good. Although the concept around the non-linear; "unstuck in time" theme explored here isn't exactly novel; the film had me entirely engaged, even the second time through. The direction, the look, the sound, all served to propel this thoughtful and ultimately very human story. Excellent performances from an outstanding cast, led by the incomparable Amy Adams, who is riveting here. Unless you're a fan of the photon torpedo type of sci-fi, this one is a can't miss.
