Everybody mixed in matrixed form for years and it took several years for 5.1 to really take hold. Thus many mid 90’s films still have very good if not better 2.0 surround tracks as that was what got the most attention-especially if theaters hadn’t paid for and new hardware or if the DD 5.1 track went out which it often did.
On the home front it was all about mixing in matrix for ProLogic with no real frills. The 93 mixes are fantastic for the time and for the most part seem to at least make an attempt to stick to the original efforts in spite of the new sound effects here and there.
