In my opinion this is a much richer film than Shyamalan's "The Sixth Sense" as you glean more and more from it from repeated viewings. Yes, the basic plot line is faintly ridiculous but the director is so adept at building a sense of dread and unease, and then unleashing some quick shock moments, that it's easy to overlook the silliness and enjoy this for just being a compelling, often amusing and really rather frightening film. What is often overlooked however is that it's also a very searching account of one man's loss of faith and of a small family trying to heal itself after an appalling tragedy.
It's a treat to have it on Blu-ray - some lovely deep dark blacks - but for my money, it's mainly to crank up the volume and revel in James Newton Howard's wondrous score.
