Chronicles of Riddick is one of my all time favorites! So I obviously already have it on Blu-Ray. Such an underrated film.
I got this Trilogy on DVD years ago. I like the movies so much that I bought Pitch Black on HD-DVD (oops). When HD_DVD died, I bought the Chronicles of Riddick on Blue-ray.
I was disappointed that The Chronicles of Riddick did not do well in theaters, but with the popularity it achieved on DVD I am hoping the sequel will do better at the box office.
I think there is enough depth in the concept to make a couple of good sequels.
