Very interesting......
18 February 2002 | by (Sherwood Park, Canada) – See all my reviews

A very interesting film especially if you are alone one afternoon and have nothing else to do. I remember around Christmas time about 2 years ago I happened to catch this film on television. All I can say is it is a very good movie and keeps the interest in ones mind hoping for the film to never end! You can bet that this film is a definite Cult Classic! I have always been interested ever since I was little in the "unknown" and the "unexplained". This great movie was made in 1975 and we all have to realise that this is when the hype with all that stuff was big. It has even been shown and explained that the largest amount of sightings for Sasquatch, Water Monsters, and U.F.O's was in the 70's. The true "terror abductions" with aliens seems to of started in the late sixties, which was a big change from the previous "abductions of grandeur" from the 1950's. The 80's seems to be the "death" of the sightings for these phenomenon and throughout the 90's and even now these sightings almost hardly ever happen, what does that tell you? Of course one theory (which I agree with) was that when this mysteries were big, others wanted attention themselves and there was a "hoping on the band-wagon" effect. No doubt that some of these people were telling the truth or at least think they did. For example: when people are at a place that is infamous for having some type of monster or phenomenon; if they see something people will automatically jump to the conclusion that it was the monster and ignore the other possible explanations. But this movie overall is very good and nicely done, 'tis quite entertaining and I suggest one to see it one of these days. I still have some belief that there are many animals out there we haven't discovered yet, especially in the oceans! I give this movie 8/10.
