A genre mish-mash that effectively builds suspense with the help of some great performances, particularly from Olivia Williams, is eventually dragged down to the soggy depths by a plot that doesn't know where it is going. Nothing is paid off, explained or really made into any kind of importance once it reaches the half-way point, as the other elements take center-stage, and by not resolving anything, it questions the involvement of the viewer into it's part of the story. An easily diverting pleasure ride, and certainly unique, but just too confused for my liking.
