I always get an excited "you're about to have a great time" feeling when I hear the music
And that's what still stops me in my tracks after all these years.
A good "saga sell" in the narration, soaring theme, and nifty (for the time) visuals.
I try to imagine what it must have been like, fifty years ago, when that first episode premiered.
A strange teaser:
"Captain's log, Stardate 1513.1. Our position, orbiting planet M-113. On board the Enterprise, Mister Spock temporarily in command. On the planet the ruins of an ancient and long-dead civilisation. Ship's surgeon McCoy and myself are now beaming down to the planet's surface. Our mission, routine medical examination of archaeologist Robert Crater and his wife Nancy. Routine but for the fact that Nancy Crater is that one woman in Doctor McCoy's past."
A strange-looking ship circling a weird-looking planet.
Then three figures sparkle into view on a desolate-looking surface. They sparkled! What kind of transportation was that?!?
Some dialog, some byplay between the fellow in the gold and the older of the two fellows in blue.
And that woman who looks different to all three men! Weird!
Then fade to black ... not black, but space. Four pings.
"Space .. the final frontier."
Mindblowing!
Back then ... .
