Pitch Black (2000)

"Pitch Black" was one if the best horror movies I've ever seen in the theater. I knew very little about it beforehand, I went in opening night with a few friends, and the theater was sold out with energized and excited people. And every one left pumped. Awesome monsters, a great and simple story, and a breakout movie making moment for Vin Disel. 

A transport ship in deep space enters an unidetified asteroid field and is badly damaged, being sucked into the gravity pull of a nearby planet. The captain is killed so two other flight crew members hustle to save the ship and themselves. The woman who takes the controls has no choice but to begin purging extra weight...including sections of passengers. She jettisons two sections and is about to release the third when they finally crash land on the planet. The remaining survivors thank her, not knowing that she killed the others and was seconds away from killing them. 

She's an ethical villain and so is the cop/bounty hunter and his "cargo", the dangerous criminal Riddick. Their petty differences quickly lessen in importance when the survivors learn that they are stuck in a planet with a very mean, very vicious creature that comes out only in the dark. And the planet is about to become a very dark place once its multiple suns set. 

Favorite moment - I love how quickly Claudia Blacks character is eaten alive as one of the first victims.
