When he said he was going to "science the s**t out of this" he really meant they were going to "Hollywood the s**t out of it." I was disappointed. The science was a little bit right, just not enough. His attempts to start working immediately on a project that he anticipated to be four years in the future was another incredible impossibility. Not that the attempt was impossible, just that he would or should know they would find him while preparing for the mission and help rather than send them 3200 kilometers from him. The incessant talking to the audience by speaking to the camera was annoying and detracted greatly from the atmosphere. He didn't act like someone in the position he was in, no reality to this movie. Another over-hyped Hollywood film.
