The Riddick movies form a really weird franchise
- Pitch Black – grounded action horror sci-fi with Aliens vibes
- The Chronicles of Riddick – zany space opera with oriental Dune vibes
- Dark Fury – an animated film that mostly riffs on cyberpunk anime
- Escape from Butcher Bay/Assault on Dark Athena – action shooter video games that are mostly congruent with Pitch Black
- Riddick – a Wild West sci-fi survival movie with shades of Pitch Black that also tries to be a sequel to the Chronicles
The only things all of these have in common is Riddick's character and the fact that they feature space bounty hunters of some sort. At this point you could probably make a Riddick movie set in the Star Wars universe, or the Alienverse or even the MCU without going particularly off-brand. I guess I'm just confused by how a series that never left the hands of its original creators (Vin Diesel, David Twohy and Jim Wheat) managed to be all over the map to such degree.
