How much of Ireland did Bram Stoker put into the pages of “Dracula?” Certainly, the country’s moody woodlands, swampy bogs, crumbling castles, and awe-inducing coastlines played their part in establishing the atmosphere of the legendary tale. According to certain folks in the sleepy, fictional, Irish town of Six Mile Hill, their cairn and its ties to the legend of Abhartach, played its own role in sparking the imagination of Stoker, who once visited the sleepy hamlet. For Eugene (Jack Rowan) and William (Fra Fee) it’s now more than a pile of rocks and something that allows them to spook the infrequent visitors who pass through. But one fateful night they’ll become the “Boys From County Hell” when they discover the legend is even more real than they can imagine in this modest and middling horror-comedy that never reaches the peaks of either terrifying or side-splitting.
