I saw the previews for this when I went to see Lust,Caution over last weekend. I'm going to see it, definitely, but it hasn't gotten here yet. It doesn't strike me, from what I saw on the screen, as a blood and guts type of movie, or I wouldn't be interested. The way this guy is killing people seems to be very calm and quiet, for the most part. Maybe I'm way off base here, because I'm basing this on the preview, but it seems that the tension takes higher precedence than the blood.
It's got to be better than Lust, Caution!
