Cold Math was an interesting one. Pitch Black as well, although as much as I live Vin Diesel and the character of Riddick, everything after Pitch Black got silly as all hell.
Doom’s story was also a favorite of mine, the concept that teleportation isn’t really supposed to be possible, so while achieving it outside of the law, the physics of teleportation allows another dimension (why Hell, of course) to come through. It’s a pity they couldn’t make a brilliant movie with the original story.
