I was only 11 years old when this first came out in 1977.  Because I was so caught up in the Star Wars phenomenon, and also because I thought (being a child, mind you) that the movie story line was a bit lame (and a bit weird with the way Richard Dreyfuss's character was), I didn't particularly care for it.  Where's Luke Skywalker?  Darth Vader?  "May the force will be with you?"  The Death Star?  The Millenium Falcon?  You get the idea.  Nevertheless, I still remember those 5 notes/tones that define it.  After a time, I pretty much forgot all about the movie.  Until I saw it on T.V. recently.  Wow, 35 years have passed since its release!  I now appreciate the story line much more, especially the human element of it, understanding human nature much more as a 46 year old adult now.  I'm not so ga-ga about the movie as the average person, but I still do like it and think it is a good movie.  Seeing such a young Richard Dreyfuss makes this movie have such a nostalgic impact, and the appreciation of the passage of time.  Not to mention, Teri Garr and Melinda Dillon are such attractive ladies.  Especially Melinda Dillon, what a cutie-pie!!  While watching the movie, I have such a crush on her!
