The film's original mono soundtrack has been reformatted to qualify as 5.1 Surround, but the effort isn't totally satisfying. There are obvious attempts to improve upon the original soundtrack, including the occasional surround effect or ambient noise. The effort is appreciated, and sounds clean. There isn't any noticeable hiss or distortion, but there isn't much surround action either. The front sound field gets the most workout, and the dialogue mix is strong and to the point.
Rear speakers make good advantage of the musical numbers, but basses are gimmicky at best.
Middle and high ends purr. Not a bad effort, but not all encompassing. Riff Raff and Magenta wax eloquent about their participation in the little film that could. Their insights are solid and interesting. I've heard most of this before, and yet I was still fascinated by the exchange of dialogue.
