Re: The Chronicles of Riddick
The Necromongers have two competing, directly contradictory motivations:
1) "To kill or convert every being in the galaxy."
2) To get to a specific region of space so they can cross over into another region of space, presumably disappearing from the space that the action has been taking place in up until that point.
One is threatening, the other is not. Either they're space-Evangelicals trying to put their Ten Commandments on my lawn or they're space-Jews wandering through the galactic desert, minding their own business.
Ultimately, it's a problem of motivation. You could have ditched their need to get to the Spatial Nether Region and just made them religious Borg. Or you could have kept it and justified their pillaging pit stops any number of ways: they need to resupply and restaff their slave ranks, they need to gather as many converts as possible to make the Spatial Nether Region Negative Space Wedgie Transfer work, they need to be stopped before they get to the Nether Region because once they do, they'll come back with super powers and THEN kill or convert everybody in the galaxy. But the movie doesn't settle on any of these, so there are bits and pieces of each, none of which are guaranteed to make sense if you applied them to a random section of the movie.
