Better than I expected, but...

Rating: 7/10 (11 August 1999)

The ads made it look really cheesy, so the film surpassed my expectations a lot (call it the Hudson Hawk gag reflex, tho Willis has redeemed himself lately - 5th Element, Pulp Fiction).
6S is a really chilling horror story to experience on screen (unlike Blair Witch, which to me is more chilling in the retelling, and will creep me out the next time I go camping). I liked the elements of Lars Von Trier's The Kingdom, Jacob's Ladder, and an old Twilight Zone that permeated it. I liked the shadowy camera effects. But, IMO, the plot twist, while clever and somewhat unexpected, negates the whole second act. I can't get into it without spoiling the movie, so I hope this is clear enough to the folks that did see it.
Still, an intelligent, well-executed film that does cater to the mainstream!
7/10
