Even though the four main antagonists don't appear much aside from several
fixed story sequences, their presence permeates each region with oppression and danger, exemplified by an army of brainwashed soldiers or zombified humans under a drug's influence.
This suits Inarritu just fine, the marketing
fixed so solely around the five minute
sequence where Di Caprio takes on a massive grizzly bear, which really is only where his
story actually begins, that the audiences are left clueless as to what the movie is really about, something few directors are blessed with in today's cinema.
