I liked the Abominable Snowman best, but was a bit disappointed they didn't live up to their handle. Still, a good film none the less.
But if we're talking Hominin flicks, you have to mention the 1977 Snowbeast, which due to my childhood terror of yetis, scared me to death, and Sasquatch 1976, which I refused point blank to see. I always regretted that till I found it on Youtube, then I realised, stick with your first instinct.
Also, there's the one time video nasty Night of the Demon 1979. I gave up aftera very short time with that one.
