“Prey” debuting exclusively on the small screen, as a Hulu original.What began as a straightforward, Joel Silver-produced action movie that saw hard-charging commandoes (led by Arnold Schwarzenegger in one of his most iconic roles) against a technologically advanced alien hunter in the jungles of South America (snappily written by Jim and John Thomas and directed with aplomb by John McTiernan) has blossomed into a vast network of spin-offs, sequels and ancillary materials. The world of “Predator” is big, bold and aside from a boneheaded, PG-13-rated spin-off, very bloody.“Prey” is no different.Set in the Comanche Nation in 1917, it follows a young girl named Naru (a star-making turn from Amber Midthunder), who goes up against the alien warrior in one of the species’ first visits to earth.
