I appear to be in the right demographic. Flash Gordon and Watership Down were among the first movies I saw. I think I saw them at the same time. My uncle took me to one and maybe decided it was too scary and moved me to another theater, decided that was too scary, and then moved me to another. I don't know exactly what happened there. I know they both scared the bejeezus out of me. And intrigued me. Pete's Dragon was also one.
BTW, Never Cry Wolf was one of my very favorite movies as a kid. I saw it again, about five years ago, and I was surprised at how good it was. It has some depth to it that I didn't quite grasp when I was a kid.
And we all know how well Flash Gordon has held up over the years!
