as a sci fi movies fan i also like alien. but pitch black is definitely better than alien 3 and alien represent resurrection. it maches well into alien series. but it isn not alien and it something else. ok and enough comparisons. this movie but me think represent why people are afraid of dark. you can not run away from dark. it impossible. you have to be faced with darkness and with that and what in dark. in this movie i also liked that the vin diesel character richard b. riddick wasn not typical good boy. he had a secrets and he has done bad things in the past. to the other people he is a hero who tries to save them all. first of all he want to get out of that planet himself. there is also other metaphors in this story. every big sci fi fan should see this picture.
