I bought Guard Post expecting it to be mostly some sort of slasher horror, with a lot of action and gore; but it turned out to be so much more!
It is actually more of a thriller/mystery/horror, and one of the best I have seen at that. Throughout the movie there are clever twists and turns which completely change your impressions of what has happened and why, keeping you on the edge of your seat. This film is almost 2 hours long and I didn't feel like it was dragged out at all!
While it is not a film that will leave you scared by its horror elements, or amazed by its few action scenes, it will keep you completely engaged throughout.
This film has very good acting and directing throughout, and comes across as a high budget film (doesn't look cheap or tacky at all), I also feel that because it is not in English it is important to point out that it has perfect subtitles and I didn't notice any translations that didn't make sense.
Overall this is a great film, but not a great buy if all you are after is horror/gore.
