In Predator, when the team makes that trap for the Predator and Dutch goes in front, the Predator gets caught. At this point, the Predator is screaming with a pitch that's inconsistent with the rest of his vocalization. Can you imagine the same Predator saying "what the hell are you?" and making all those growling, roaring sounds, screaming like that? He screams like some kind of monkey throwing a fit.
It's not a big deal, but when I think about it, it slightly gets me out of the zone.
