The movie was aired in the children's morning program in Hungary (by the name 'Farkaslak' which translates to Wolf's Home) when I was 10 years old, some 20 years ago, and I must say, it scared the hell out of me! I expected another Czecho-Slovakian youth movie, the kind which flooded Hungarian television then, but what I got was something really extraordinary.
The shocking scenes with the dead girl in the snowman, or the strange movement of the aliens (?) definitely burned themselves into my mind for a life! There are no 'classic' horror elements in the movie, it rather operates with psychology, quite successfully. It would be interesting to watch it now as an adult. Maybe then I could sleep better on lonesome winter nights...
