Maybe, for technical aspects, this film just works wrong . But, as one of few viewers not interested by blast off into orbit from astronautic perspective, for me enough remains the story. Who is far to be the worst. Sure, too sentimental, giving a nice sketch of loneliness in space, proposing almost mioritic attittude but , in some measure, fair refuge to happy moments front to imminent danger. It is difficult to say if the astronaut, at the end, sleeps or he is dead. But, in bizarre way, this becomes only a very less significant detail. So, an emotional story, too sentimental, off course , but working in decent way first for message.
