As much as I want to see Riddick, the third movie starring Vin Diesel as an escaped convict and murderer as anti-hero, I think someone lost track of what Pitch Black, the first movie, was about. Riddick was a big part of that story, but it was a story about redemption, forgiveness, trust and cooperation in the face of life-threatening danger. By contrast, the sequels are about Riddick being an amazing badass in the face of explosions. That's not a story at all.

PPS - Right now, I'm not too cut up about that.
