Yes, set it in Mogadishu.
US forces are unlikely ever to go back there.
Yup, which is hard to see for a human. Predators aren't humans. The end. Movie shows he can track, he can track; your inability to distinguish people from a distance doesn't mean it can't.
Dude, it's just stripes of colour. The Predator can't magically see something in it you and I can't. That's what the mask is filtering and that's what it sees. Until we get a movie which states otherwise, it can't discriminate faces at a distance
We can say they might
be telepathic or might
have microscopic little tracking devices, but the movie doesn't show those, either. Based purely on screen, once it's got
prey on screen, it'll be very good seeing where it's (immediately) gone, but their version of heat vision is rubbish for facial recognition.
And we certainly don't see any 'Terminator 3
'-style graphics of the mask zooming in on a fingerprint database or an iris ID, either.
And, see, this is what should
happen. Predators aren't omnipotent. They've got tools which are amazingly good for certain situations, sure - but are going to be piss-poor in others. Just like human beings have.
