They're a good fun couple of movies to watch. Nothing outstanding or amazingly original, but I still enjoy them.
PitchBlack and Chronicles of Riddick are two of my favorite sci-fi movies of the past few years. You need to watch Pitchblack first to understand Chronicles. Vin Diesel used to be a bouncer in LA. x
The look of the Chronicles of Riddick film was terrific.. too bad there wasn't sufficient story to backup the aesthetics of it.
