This is a nice addition to the post apocalypse genre. Well, I say nice ...
I love grim fiction. The bleaker the better as far as I am concerned. And yet this is unrelenting in it's gloom, indeed some scenes are so darkly lit it is difficult to see precisely what is going on. Most of the time, though, this serves the horror well. The 'zombies' here, or the undead, are shrouded in shadow, and literally do leap out of the dark. This may be due to the small budget - there are only three primary cast members - or it may be more deliberate, and there is no denying its impact.
Equally, the distant howls of macabre anguish carried by the gales on the unforgiving Scottish scrublands - always filmed in gritty, cold colour - are a reminder of the constant threat 'out there', and is much more effective than a handful of gored-up extras hovering in the background.
There's little new attempted in the storyline, but it is a compelling journey. The message seems to be 'compassion is a weakness', although it is precisely that which drives Daniel and April together. It also invites stranger Kate to join them for a time, before they are exposed to the dangers of what happens if you let the outsiders 'in'.
The performances are great, and the direction and sparse soundtrack are terrific also, apart from the occasional hard-to-define scenes. More Night of the Living Dead than 28 Days Later, there are many scenes with little or no dialogue, and little is explained; we are given clues as to the past (for the most part) with flashbacks. And it ain't pretty! Recommended.
