Well that has cleared the 3 #Riddick movies out of the TiVo, watched in order for the first time.
Some of the dialogue in the third movie is Riddick being oblique, and only really makes sense if one has actually seen #PitchBlack, which as I recall wasn't the case when I first watched movie 3.
It's basically a #SciFi slasher movie with a bit of man+dog buddy movie (Sci-Fi style) mixed in. #TheChroniclesOfRiddick is still the best one of the three by a significant margin.
It's interesting that movie 1 had Australian locations and several Australian actors, and movie 3 was Canadian locations and mostly U.S.A. actors.
Also interesting is that the set-up for what we know about the forthcoming movie 4 has been dangling at the end of movie 3 for 13 years. Movie 3's dialogue established a 10-year in-universe gap from movie 1, the real world gap being 13 years. I wonder whether it is going to be another decade in-universe.
