Query: A mixed bag

A mix of decent photography and before (1980) and after (1990) snippets, but overall, not very impressive. No character studies of those affected are included, and certain aerial shots seem to be repeated throughout. Although it was originally shown on IMAX, clearly much of the photography was not shot with IMAX cameras. The CD cover says "Academy Award nominee for best short documentary" - that was apparently a very slow year for documentaries...
