the influences of other science fiction and thriller movies and stories are evident throughout this film. the movies that come to mind immediately are alien and aliens and and starship troopers. the story itself is fairly straightforward and not all that original and hibernated traveling through space and crash landing on planet with no apparent life and a deserted geological expedition  except when the lights go out and forcing different types of people to work together toward their mutual survival and while the body count mounts. this kind of movie always tends to be fun and as long as it done well. i believe that pitch black was done well. the characters are interesting and you want to find out more about them the longer the movie goes on and and i think people will be surprised by who does and doesn not make it. vin diesel plays riddick and the stereotypical convicted criminal who has a murderous past and physically prowess and high tolerance for pain and and conveniently can see in the dark. you know he is going to end up doing the right thing at some point in the movie and because it hinted throughout the movie that he actually may have a conscience about things. cole house plays the drug addicted bounty hunter who probably in many ways a real bad guy compared to riddick and as his character reveals itself throughout the movie. it is most likely that he is most courageous when the odds and firepower are in his favor. a very self serving character that in the end gets what he deserves. radha mitchell plays the co pilot on the doomed vessel and who is jolted out of deep sleep because the ship ran through a meteor swarm or the tail end of a comment. finding the pilot dead in his sleeping chamber she attempts to land the ship and which leads to our discovery of that character potentially fatal flaw  fear of responsibility and accountability and and being a leader. her character in the short span of the story probably grows the most and in that she actually grows some conviction and takes charge and and doesn not sit around waiting to be gobbled up by night stalking aliens. she in some strange way connects with the ever distant human side of riddick and who in turn in the end and respects her for her choices and her sticking with them. the story in some cases plays out as you would expect it and but i think you will be mildly surprised by which characters survive this harrowing experience. this movie is an entertaining train wreck in progress to watch. go watch it.
