With no aspirations to be a franchise, this is a very effective low budget sci-fi thriller. Twohy makes very clever use of his budget, through cinematography that helps to sell the otherworldly environment and a concept that allows him to hide the primitive CGI used for the creature effects. After a great opening crash landing, Twohy gradually builds up the tension to the inevitable eclipse and whilst most of the cast are essentially there to be picked off one by one, the three core central characters are interesting and developed well and unpredictable with a very effective moment of redemption and closure at the end. It is easy to see why more films were made as Riddick is the standout character, but both Radha Mitchell and Cole Hauser make an impact too. There are some great tense moments in the darkness and clever use of limited Iighting.
It's all about the information, not about guns and money. The story is more relevent then ever.
