10 Incredible Endings To Otherwise Terrible Sci-Fi Movies

The biggest mistake involved in the production of 2005’s Pitch Black sequel Chronicles of Riddick was the decision to convert David Twohy’s intense, hard-R original into a more family friendly PG-13 sci-fi action series, resulting in a toothless instalment which proceeded to leave audiences uninterested in the further adventures of Vin Diesel’s eponymous hero.
