So, is it The Watchers or is it The Watched? In North America it’s the former, in the UK and Ireland it’s the latter, and it’s a testament to the all-over-the-shop plotting of Ishana Night Shyamalan’s feature debut that it doesn’t really make much difference whichever way you look at it. Working from a folk-horror novel by A.M. Shine, Shyamalan takes a simple single-location genre premise — literally, it’s a cabin-in-the-woods story — and somehow creates a thriller that’s both unnecessarily complex and almost entirely uninteresting.
