This film was very low budget and lacked funds for effects in a genre that usually thrives on them. It's difficult to shoot lasers from a CGI gun and it's even harder to pull off being weightless without hanging from wire. But although the lack of effects that our movie-watching culture has grown so used to makes scenes seem awkward and sometimes a little slow, the film is very well carried by our star, Billy Boyd. The themes of this film which surround lonliness, isolation, and helplessness are played almost wordlessly. The gaze of Boyd's eyes seem blank most of the time but we soon come to find out that perhaps he's contemplating a severe lack of meaning in his life. By showing his boredom and disinterest he reveals that he's lost affection for his mother and his assumed girlfriend. He vaguely plucks the strings of his guitar creating no music just noises that he doesn't even seem to pay attention to. The very sight of him trying to masterbate while strapped to a wall (zero gravity - SCI-FI!) and with nothing but virtual goggles for stimulation shows that an act which is usually associated with a feeling of freedom and euphoric wrecklessness has to be severely controlled and is now impossible to enjoy. I don't want to be a brat and spoil the ending but I will say that the outcome of the film seems to be a closure for Boyd's character as there seems to be no other possible option as an end to his mundane life in outer space.
