wasn't the thunderdome 5.1 mix derives from the 70mm 6-track audio?
Are you referring to this review? That guy makes the leap that the 6-track mix was 'presumably' the basis for the 5.1 - unfortunately that is far from a given, it being much easier for the studio to do some roughly directional upmixing on a 35mm mix source.
Still, it's good to hear that people are liking the BD track - I'll certainly listen to it properly before dismissing it entirely (particularly in the absence of a laser track to use).
