Just watched the Blu-Ray, solid transfer with good audio and video.
The film really falls short of being a horror film for me though, perhaps suspense would be a more apt category. In spite of this I really enjoyed it, there were some good tense moments and the acting, especially on the part of Paul Le Mat and the kid in the lead role was quite competent.
It was quite slow in parts, and there is little gore or T&A to speak of, but still a pretty effective thriller. Definitely would not fit in the slasher genre for me, despite having some of that genre's hallmarks.
