I thoroughly enjoyed this movie but I am a Keanu Reeves fan. It was thought provoking; which family member would I have to delete if this happened to me and to what extremes would I go to keep my family alive. Some of the scientific procedures seem illogical, especially the timeframe within which they are executed, but it isn't a documentary. I don't understand the bad reviews. I go to the cinema to be entertained and the movie was entertaining.
