As other reviewers have noted, if you're looking for an "Insanitarium"-style splatter-fest then this film is not for you. The first hour of "Dark Song" is a mysterious, deliberately-paced psychological thriller with two interesting characters stuck together in a house for months, feeling each other out. An occultist (Joseph) is trying to help a woman (Sophia) contact her dead son. This requires dark rituals, fasting episodes, and sleep deprivation. Their motivations and honesty are both in question, leading to plenty of dramatic tension. What's real, in terms of both past and present? Who's lying to whom? The film takes its time exploring these questions, and for the first hour at least, the viewer's patience is well-rewarded. I especially liked Steve Oram's occultist character, who doesn't fit the classic mold of "actor" or "hero" one bit, and is all the more fascinating for it. I won't go into deeper detail for spoiler reasons, but suffice to say that both characters fall into the logical traps of mistrust, manipulation, and frustration after being cooped up for so long.
My problem with "Dark Song" was its ending. It made sense from a dramatic standpoint, and of course there were several directions it could have taken. The fact that I wasn't satisfied doesn't mean you won't be. But along the way I had some really freaky ideas that I hoped would be explored, and they weren't.
In any case, I still recommend "Dark Song" as a mature, well-made, and disturbing psychological thriller.
