Trekkies: if you see this post your first experience with Star Trek. I have clear memories of catching bits and pieces of The Motion Picture on HBO when I was 5 and the next year began a TBS re-run of TOS in order. Mom watched it religiously as she'd been a fan of the original broadcasts.
She used to talk about how when the first jets started flying over her little corner of nowhere, Mississippi, when she was a kid, her dad would fuss about it looking like Martians coming to invade. She said she secretly hoped it was Vulcans coming to make first contact. 🖖
I had fleeting experiences seeing the original series in prime time when I was pre-K age. My mother didn't approve of Spock; she thought his ears made him look like the devil. I was terrified of the giant flying witches' heads episode.
