One of the most impressive uses of sound in the Blu-ray version of Men In Black is when Will Smith enters MIB's "lobby" - the Fan Room for the tunnel. Those fans make the room shake!
I've one thing to contribute about Independence Day - the Blu-ray version is based on the theatrical version, not the extended version previously released on standard DVDs. As a result, scenes that helped to establish character, particularly in the crop-duster's family, along the route of the truck that Will Smith's fiancee commandeers, and in Area 51 (sorry, Data), were left out of the (initial?) Blu-ray version. Are they setting us up for a later "extended version" release, replaying DVD's habit of going to the well repeatedly on a major picture? It looks great, however, and its sound is good too - complete with moon-shaking sound when the invading ship passes overhead, stirring up the dust.
