I remember watching this movie in great amazement when I was a child.  It is such a great movie.  When I'd heard that it would be on DVD I had to rush out and get it.  I watched it with my ten year old stepson and he watched it with the same enthusiasm that I remember in myself.  Close Encounter's is truly one on the classics.  A wonderful movie to watch with your family.  If you've not seen it, you need to.
