Harry stayed up late to see Santa once as a child in the '40s and witnessed 'Father Christmas' make love to his mother. Dismayed, he grows up to become obsessed with Santa and works in a toy factory. His home is filled with Santa memorabilia and he is even spying on the local children and keeping his own (rather elegantly bound) naughty and nice lists.
Throughout the film Harry begins to unravel further until he eventually snaps, going on a rampage in his Santa costume (complete with glued on beard!) that is part killing spree and part burglary, charity run and party entertaining.
An odd film. There are scenes of gore, but primarily this film acts more as a social commentary on consumerism, mental health, innocence and the sad side of the holidays.
Harry cuts a sympathetic character, not a monstrous serial killer. And really he's just trying to be a good Santa for the good children and punish the non-believing adults. In his own twisted way, he's doing the right thing... It's just that his moral compass is a little off.
It's neither good nor bad, it just kind of IS.... Vague, I know, but it was just a weird one!
