Premise: It growls and snaps at the air, and though it does manage to stomp one victim (who, in a nice touch, sticks to the bottom of its foot like a piece of gum), in general it moves with such a lumbering gait that we might as well be back in the '60s watching Valley of the Gwangi . Where is the lethal swiftness of the predator?

Hypothesis: The predator was never able to kill a victim.
Relation: contradiction
