Riddick is the third of the series that started with Pitch Black which had some excellent ideas, but with a few poor executions. After a definitely better sequel, called The Chronicles of Riddick it goes back to its root with this chapter. Fortunately, the budget was on hand to make it better than the first. However, the edge it lost in the second installment isn't back and it's not as solid as the second one, but the fun is still there. The end is weak.
A must for fans. The others can still enjoy, especially if they like action or sci-fi with monsters.
