The soundfield isn't overly ambitious, but it provides a fairly full image. The front channels dominate and offer sound that's spread broadly across those speakers. The surrounds tend to mainly bolster the music, with some occasional but rare effects as well. Sound quality seems consistently excellent. Dialogue appears clear and natural, with no intelligibility problems.
Effects are clean and realistic, and the music seems full and bright, with strong dynamic range.
If the quality displayed any faults, I couldn't find them. All in all, The Sixth Sense offers a fine audio experience. Most of what we find comes from video interviews with many of the main participants. However, this is really Shyamalan's show, and his presence dominates the supplements. Happily, he seems like a nice guy, and he presents an unassuming, modest and likable personality.
