Been wanting to see the original in good quality for a while. The directors cut was an abomination my biggest beef with that beyond the CGI its not Walter Murch's mix.
The original Mixes on American Graffiti and THX 1138 were impressive.
I don't have the Graffiti BD so cannot comment on whether it has the original mix or not. I figured it would have some new fangled 5.1 monstrosity.
