My wife and I watched this last evening, wondering all the while why the story was being told with the chapters in reverse order. We needn't have wondered. It becomes clear that the story wouldn't work well in reverse, as the big reveal comes in chapter 1. The story is interesting, and the acting passable, but where the movie falls down is in the casting. It becomes clear at the end that Alena and JB are of approximately the same age, whereas in the other chapters, this does not appear to be so. The actors portraying them have 14 years difference. With all due regret, it is also difficult to imagine Tom and Alena as a couple. JB and Poppy have 19 years difference. Jonas Chernick is simply too old for his part. He ought to have stuck with writing the story, which was fairly well done.
