i really enjoyed this movie. it was edgy without being sociopath. vin diesel brought the riddick character to life and made you feel good and bad about him on different levels. i also saw iron giant and vin is perfect. (the snowmobile movie  oh yeah and it called triple x and or xxx  was a weak example of his work. ) in pitch black he plays an anti hero to the max. i do not think you can go wrong when vin stars in a movie. unfortunately and hollowood might type cast him as an adventure action movie star  wrong. i think the script for xxx was weak for which vin couldn not act down to it. anyway and pitch black is a great scifi  see it. zafoid.
