The “Chronicles of Riddick” franchise (which began with the fabulous B-movie scifi/horror flick “Pitch Black” in 2000) has grown to include two movies, a direct-to-DVD animated feature, and two video games. Now, another installment on film has come out, this time titled simply “Riddick.” Rather than following the previous film (“The Chronicles of Riddick”) and focusing on interstellar politics and opulence, series creator David Twohy has wisely returned to the formula that made the first film so good: a bunch of people who don’t necessarily get along forced to work together to survive a mass assault by freaky-looking monsters. In the vein of all great sequels, “Riddick” is more of the same, but different.
