And we wonder if everything that happened to the hero is true, or if he's dreaming. Bill has problems and disappointments, but he is quite balanced for Kubrick's protagonist. He is even-tempered, polite, generally balanced, a good parent, sympathetic to working class people and eventually confesses his affairs to his wife.
The action takes place at Christmas and in the opening scene we see a festive party, but overall this doesn't play a big part in the plot.
The film is accompanied by an absolutely stunning soundtrack, which gives the film an unsettling atmosphere. The entire film, especially the scenes during and after the masquerade, carries an overwhelming sense of dread. We know that something sinister is going on with the cult and its actions, but we never find out exactly what it is. It's even more disturbing to think about what the cult might have done to the masked woman who sacrificed herself to save Bill, assuming Ziegler is lying.
