I recall reading an interview with Ronald D. Moore (creator of the re-envisioned Battlestar Gallactica) where he talked about being a such a fan of the old Star Trek that he recorded the audio of the show by putting a tape recorder in front of his parents TV. He would then fall asleep listening to the show. He said that to this day he responds more to the audio cues in the old series more than anything else.
I totally know what he means right now.
Also, it is amazing how much work the melodramatic music by Alexander Courage is doing to keep the audience excited. It was really a very heavily scored show.
