Do not expect aliens, monsters, scientific theories or thrilling action scenes. Yes, the movie begins with a wonderful sci-fi premise - similar to those in Kurt Vonnegut tales - that life after death is real (for some people), but this is not a ghost thriller. However, like all great sci-fi from Frankenstein to The Thing to Hellboy to Avatar, this movie explores the issues of "the nature of human life' and "what is it that haunts us." It is a slow burn, ok, but it fills the slow spaces with realistic, natural humor. The acting is superb. The directing and script are compelling. The pay-off at the end is satisfying. You don't even need the "sci-fi premise," because everyday my true-believer Christian friends try to convince me that the afterlife is real. So, I ask ... why not die and move on to "the better place?" I enjoyed seeing these characters trying to explore their reasons for dying and their reasons for living. I can't give it a 7, but it deserves more than a 6. I was pleasantly surprised and impressed by this one.
