Good forgotten scifi.
I give this movie a 'good' for its plot, and acting. And the ever-present fog gave it a bit of a 'creepy' atmosphere. Unfortunately the low-grade dinosaurs hold it back. When I first seen it on TV, I was young and unable to grasp how there was an isolated prehistoric region in the arctic ice.
And even then I was not impressed by the quality of the dinosaurs. But it stuck in my mind as another form of "The Lost World". But at the Polar region, not on a platau in Africa or South America.
I now, years later, have purchased it just to review how the hot and steamy dino-land was possible in the Arctic. The extinct volcano concept would still hold up today, if not for our modern satellite recon and mapping.
Anyway, as a lover of any 'lost world dino lands', I would recomend this oldie to others of like mind. Not at the top of your 'must get' list, but not to be forgotten either.
