Blacks are accurate looking and the level of shadow detail is about what one would generally expect from an early 1980's production. The Dolby Digital 2.0 channel soundtrack decodes to standard surround, but as with the second installment, is unimpressive. The forward soundstage has a decent amount of activity and channel separation has cleaner definition that what was found in the second film. Surround usage is relegated primarily to ambient sound, but there are occasional active effects. Age and limitations in fidelity keep the sound effects from having an overly convincing presence.
Dialogue has better intelligibility than number two, although the voices sound a bit flat at times.
As for the music, Ken Thorne is no John Williams, so you aren't missing much listening to the uninspired score at a limited level of fidelity. A French monaural track is also encoded onto the DVD, as are English, French, Spanish and Portuguese subtitles. Music underscores the basic interactive menus, which provide access to the standard scene selection and set up features, as well as a theatrical trailer and cast filmographies. Because I loved the first two installments, I take offense at this film and become even more offended every time I see it.
