Exhuma  has a predictably Eastern horror flavour, as might be expected from a South Korean production. That said, many of the horror elements expanded upon in  this film, cross cultural boundaries, resulting in an, at times, chillingly ghoulish experience. 

Scenes of the dead resurrected, as evil spirits and ghouls, are not to be underestimated in their scare potential. They are well done, with a strong sense of realism, creating an atmosphere of creeping dread. 

Where this film might be a difficult one for Western audiences, is in some of the Eastern, if not Korean, cultural and religious/supernatural nuances of the film. I for one, found it a a challenge at times, to gain a cohesive understanding, of the overall story, for this reason.  

In summary, a great deal of scare potential on offer, with what is a familiar but at the same time, uniquely Eastern tale, of evil, from beyond the grave. You might struggle with certain aspects of the film, if you are from the West, but its certainly well worth the effort.
