Disappointed that the plot wavered between supernatural and plain bad/mad people, then left us hanging with the carved flint spearhead, a menacing Alsation and Rob/Adam's unrequited love for Cassie. We didn't find out who Lexie was. We didn't find out what happened to Jamie and Peter. We didn't find out why child Adam had cuts on his shirt and someone else's blood in his shoes. Too many questions unanswered. Not helped by confusing time shifts, and poor sound - the dialogue, with necessarily strong Irish accents was not easy to understand due to muffled/quiet delivery. I was gripped then dropped at the last moment. However, that may have been the artistic intent of the production, I guess.
