I found this movie because of a personal connection (my mother was a high-school classmate) and conversation with writer/producer Bobette Buster. So in some ways, I sat down to watch this out of a sense of obligation. But after a conversation with her, I was intrigued and very interested in this movie.
It was fascinating. I don't consider myself to be a cinema connoisseur, but the history of sound in movies was utter fascinating. I my conversation with Ms. Buster, I happened to mention Apocalypse Now, which features prominently in Making Waves. I love the iconic 1/9 Air Cav scene with Lt. Col. Kilgore (I refer to Ride of the Valkyries as "Charlie Don't Surf" by Wagner), and it was really amazing to see all the work that went into that scene and movie.
It was also instructive to realize how integral sound was in making scenes iconic.
Highly recommended even if, maybe especially if, you're not a student of cinema.
