Even as a kid I liked everyday life type movies better - not syrupy, so much as stories I was interested in. So.. of the many type big animal movies, the only one I ever saw, by no choice of my own at the time, was Mighty Joe Young, the 1949 one. Don't ask me what it was about! I probably saw it in '50. Huh, I just read the imdb on it, and I recognize the original story writer's name - my dad knew Merian Cooper.
So, having just read the imdb with the story, I might like the movie now, 65 years later. Off to Netflix I go.
