Before age 10- I’d say my favorite flick was Sound of Music. Between 10-15, we began to discover the video store and I was in love with Raiders of The Lost Ark, Star Wars and All of Me (still awesome Steve Martin/Lily Tomlin flick). We also loved Uncle Buck, and all the John Hughes high school films.
I’m 37, my favorite film now is Trainspotting, go figure.
When I was a kid in the 50s, Million Dollar Movie used to show the same movie every week night at seven PM for a week, and about four times each on Saturday and Sunday. Whenever King Kong was the movie of the week, I would try to watch as many showings as possible.
I watched The Dark Crystal a billion times, even though it scared me. We rented it and I had my parents make me a copy, which was done with about a million miles of coaxial cable from their bedroom to the living room.
I was all set to whine that the OP could only be answered by kids who grew up with VCRs, but you reminded me of Gravesend Manor on WOI-TV (Ames, Iowa) on Saturday nights. We grew up watching the Universal classics – Frankenstein, The Wolf Man, Dracula, The Mummy, The Invisible Man, and all the Returns, Sons, Wives, and Daughters they spawned. Good times! My favorite was Frankenstein.
