You know what happens when a painfully mediocre film based on a great concept makes a little money at Fox? They set out to make an even worse hunk of mediocrity. So... set off the confetti cannons - another nail in ALIENS and PREDATORS' coffins is being hammered...
Whoa, wait a minute. Who ever said that "Alien versus Predator" constitutes a "great concept"?
And yet, the film apparently made enough money to make a sequel a justifiable business decision, in the eyes of the Fox people. I think that should be another nail in the "People want good movies with good scripts" shibboleth, eh?
I often hear the refrain, "When will Hollywood just go back to making good movies?" The answer is, obviously, that Hollywood will go back to making good movies when people stop paying to see the shitty ones.
