I saw the Chron. of Riddick today and it was a pretty good Sci-Fi action movie. The cool thing about the first movie, Pitch Black, was that Riddick was mysterious. In this movie they take away a lot of that mystery. Instead of watching a movie about a cool anti-hero, we are left watching a fun Vin Diesel movie. I would give this an eight out of ten and think any fan of action, sci-fi or B movies will enjoy the ride.
