A horrible pastiche of too many other films and books.

At the core, it's a cross between The Spirals of Danu and The Warhammer novel "The Unkindness of Ravens", but without the mythos or sophistication.

Clunky dialogue and mile-wide-plot-holes make this boring by the numbers "horror" (and I use that term advisedly) one to avoid.

A well done independent movie, beautifully shot in the Scottish Highlands, that blends the horrors of PTSD with the fascinating Celtic legend of the "raven warriors". Atmospheric and unsettling, with its low budget only revealed with some dodgy CGI.

Have you seen The Birds and First Blood, original avian terror and disgruntled war vet films. Then there's nothing new here as with all films today, same old same old. But half an hour waiting for something other than characterization or scenic ambiance is too much. be warned the great reviews seem to be those who invested in this, I'd rather watch aforementioned or Alien / Predator / Terminator for the umpteenth time, anything with a new slant.
