Holy shit. Not only is this incredibly R-rated new trailer for Riddick delightfully violent, it's also genuinely scary. It's like a blood-soaked reminder that "Hey, sure Riddick was kind of the hero of the last movie, but you might want to remember he's also an amoral killing machine who is very, very good at his job."
Vin Diesel is really easy to rag on but he totally owns this character. It's such a pleasure to watch. I loved every second of that trailer. Riddick is Diesel's Snake Plisskin and if all of this is just a rehash of Pitch Black, so be it. We live in an age of reboots and sequels anyway. Might as well give us something badass.
