Based on the Japanese light novel All You Need Is Kill, Edge of Tomorrow features Tom Cruise in a Groundhog Day (1993) style time loop, in which he battles against aliens, gets killed, and repeats the same day, over and over again. An important improvement over Groundhog Day can be found in this movie: a reason is actually given for the repetition, and that reason has a consequence that determines whether or when this supernatural ability stops.
As an action movie, it is thoroughly entertaining and remains interesting for the whole time. It successfully shows that even with this supernatural ability, winning the war is anything but easy. There is a romance element here but it is not developed deeply, which is understandable since every day everybody’s memory is reset except Cruise’s character. The only really major flaw is the epilogue, which makes no sense in terms of its own rules. Nevertheless, this is still a significantly more entertaining movie than Tom Cruise’s previous sci-fi movie Oblivion (2013).
