Watching a snowflake slowing melting would be more entertaining than this "goes nowhere very slowly" painful to watch film. It's so bad that I could not watch any longer than ten minutes at a time.
Zero sense of danger or tension and the characters were so bland that an audience would not care in the least what happened to them, buried alive under snow, don't care if they are. Nice scenery is the only positive but this does not compensate for the many negatives in it.
Don't waste any time watching this, I had trouble finding it on IMDB as it was made in 1969, and it looks it, and not in 1994.
