In Pitch Black, the silver-eyed, night-visioned convict Riddick (Vin Diesel) was the anti-hero, the untrustworthy guy driven to good by interplanetary beasties. In The Chronicles of Riddick, director David Twohy again asks Riddick "to save or not to save": The Necromongers are going planet to planet, mongering muchos necro, and nobody can stop 'em -- unless Aereon's (Dame Judi Dench) prophecy comes true. (If you think "Necromongers" is bad, it's only the start: Everything in this film was named by a 14-year-old with Latin for Dungeon Masters and a Star Trek DVD set.) Unfortunately this time, no matter how often it's said that "Sometimes the only way to stop evil is ... with another kind of evil," Riddick's character is never in doubt. What it lacks in character depth, Chronicles makes up for in, like, totally awesome fight scenes in strobe lights -- if you can even spell "seizure," take heed -- starring Riddick and The Hot Chick That Can Totally Kick Ass (a.k.a. Kyra, played by Alexa Davalos). Bigger-picture check: As a comment on the moral ambiguities of homogeneity and the powers and dangers of faith, Riddick does a great job of ... having, like, totally awesome fight scenes in strobe lights.
