There’s some interesting things going on in this movie –
There is an apex predator in the movie, but it’s not Andrew. It’s Matt. He pretends to be Andrew’s friend but doesn’t help him with any of his family problems. He uses Andrew’s concern for justice and fairness and various problems to act as the noble guide. He loves another sham (the would-be helpful Casey) and at the end of the movie celebrates his conquest by eternally fixing the camera at a dead place while his two dead “friends” are buried in the ground. Andrew’s view of himself as the apex predator protects both him and Matt from the truth – the movie is about the lengths Andrew goes to to express his love for others as well as Matt – a sociopath without the capacity to receive love.
