This is a revised review of my previous...because I need to echo once again how amazing this set is.  Bluray is such an incredible, versatile, and exciting format.  Close Encounters is the kind of transfer which is why I bought a BD player to begin with.  It contains all three versions of the film, so if you're partial to one, it's here.  It has been so meticulously remastered that it looks like it came out last year.  It was like seeing it for the first time, every detail from the knick-knacks in the Neary home to the detailing on the alien craft are rendered beautifully.  Each film has 2 lossless sound options, which is almost unheard of.  A DTS-HD MA and a Dolby True HD 5.1.  I prefer the DTS, but both are very powerful.  Not only does it feature house-rattling bass, but ambient and directional effects are exhilarating.  Dialogue reproduction is crisp and spot on.  Simply put, it will never look or sound this good again.  It was restored from the original source.  This was the first of Spielberg's oeuvre to be released and the follow-up have not been disappointing.  "Minority Report" is a revelation, "War of the Worlds" and Saving Private Ryan" ...all of these are demo-worthy, reference grade transfers.
