Ben Mendelsohn and Laura Wheelwright as 'Pope' and Nicky

Animal Kingdom is an excellent, tense and believable film, and is well worth watching if you want to try to analyse how the emotional effects are achieved with subtlety. The characters retain interest and complexity, and observing the way they disintegrate under pressure is compulsive to watch, accompanied by mounting unease and horror. It is a realistic portrayal of normalised deviancy, and Ben Mendelsohn's character of 'Pope' undergoes a riveting gradual transformation from the least scary character into a figure of nightmare via a horrifying and (probably) unexpected twist. All writers can learn from good writing in any media, so don't discount close observation of a film as being a good source for analysis.
