My little brother adored this show as a little kid, probably eight years old and completely dino obsessed, and years later in isolation induced nostalgia he asked to rewatch it with me (I didn't really watch it with him before).
The writing is awful, the science is worse, the characterization is inconsistent to the extreme, and it's clearly propaganda (though at least it's goal is a positive one), but in a house where very dumb show or movie becomes Mystery Science Theater: Home Edition, watching it was an absolute blast. And you know what, they may play the theme song half a dozen times in every episode, but it's still a darn good theme song, I won't lie.
