Set in a bleak, unrecognisable, present day, breakdown-of-society, Ireland, 2 couples survive (we assume for the titular One Hundred Days) with no electricity, no weapons and with a simmering tension threatening to break through at any moment.
This slow burner uses tension and an intelligent script to cover what its budget lacks. The couples do their best to survive, always hoping that an end to their troubles and a return to normal life is just around the corner. Despite living in close quarters to their new age neighbour, no-one truly trusts anyone else and the threats of danger and possibly death are always around the corner.
Many viewers will be left troubled by the ambiguous ending which simply ends on a muted note. If, however, you want something which doesn't rely on gore, lavish effects and fake scares, then this is the film for you. The beautiful landscapes and excellent performances more than make up for what the budget lacks and the depressingly dark feeling of the film should satisfy fans of the post-apocalyptic genre.
