Lots of great actors, great special effects and great idea for a movie but ......no scientific research and a story that seemed to be written quickly without much deeper thought than a screenplay from a middle school theatre project left me very disappointed.
To see a better movie with a similar theme try Light of My life with Casey Affleck or The Road, The night eats the world or really an apocalypse movie besides this. Im sorry because I really like these actors and wanted it to work. Ultimately it was the producer that ruined the film because it should have been checking the content before it was released.
