These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Buck Rogers in the 25th Century aka: Buck Rogers In The25th Century
The pilot movie actually began with a song version of the intro theme music. Video copies of the pilot movie title sequence have been removed from YouTube, but an audio-only rendition can be found. For extra kitsch points, fans of The Lawrence Welk Show (by which time there were veryfew left) were tickled to learn that the singer was the Lennon Sisters' kid brother, Kipp.
The pilot movie (complete with theme song) is part of the DVD collection of the series.
