The plot has more holes than the hull of Fry's spaceship.

Rating: 5/10 (5 December 2015)

A deep-space passenger ship is hit by meteorites that breach the hull, forcing pilot Fry (Radha Mitchell) to crash-land on a nearby planet capable of sustaining human life. Incredibly, Fry and a handful of her passengers survive the impact, including mercenary Johns (Cole Hauser) and his extremely dangerous prisoner Riddick (Vin Diesel).
After investigating their new surroundings, the survivors come to the conclusion that they are on a dead world, all indigenous life having long been wiped out. In fact, there is one species still very much alive: flesh-eating, light-sensitive creatures that live below ground, away from the deadly glare of the planet's three suns. Unfortunately for Fry and company, they are about to be plunged into darkness by an eclipse that occurs once every 22 years, and which signals the emergence of the aliens from beneath the surface.
The survivors only chance of making it off the planet alive involves transferring energy cells from their downed craft to a functioning ship discovered at a nearby deserted mining colony, a task that requires putting trust in Riddick, whose surgically enhanced eyes enable him to see in the dark.
I'm willing to forgive the whole convenient 'breathable atmosphere' issue (as I do for one of of my favourite sci-fi films, Enemy Mine), but sci-fi horror Pitch Black throws up one unbelievable plot contrivance after another, completely ignoring logic in favour of thrills, thereby making it hard for me to rate it very highly despite some well handled action from director David Twohy, a memorable turn from gruff star Vin Diesel, and sexy Radha Mitchell in tight clothing.
The silly plot simply leaves too many awkward questions: if the aliens have long eradicated all animal life on the surface, what the hell have they been eating ever since? How do creatures that burn up in daylight but which must come to the surface to feed evolve on a planet with three suns? Why do they even bother to come to the surface if they've already eaten everything? Just a few of the head scratchers that this poorly scripted flick fails to answer.
