Attention to detail isn't precise but good enough not to make it an issue. The soundtracks are functional but present no challenge to your sound system. Delivered in the respective film's original mono soundtrack, the digital transfer sounds clean most of the time. A little background hiss in some of the quieter moments, but not earth shattering. Dialogue mix is strong, but don't expect too much more.
Ambient noise is okay, but there's no bass action.
Poor No closed captions or subtitles. Fit An excellent gift for the mature mystery fan in your life.
