This is a perfect example on how well a movie can be made with few characters and limited amount of budget at hand! It's really how amazing that they have had an estimated production budget of just CA$115000 and came up with this beautiful Canadian baby.
Right off the bat the director establishes the dynamics between our main leads(Fred and Janet) and tension starts to build slowly while they were on their way to a friend's house. On their way, while Janet was asleep Fred decides take a different route via a small countryside where people live apart at least 10-20 miles from each other. When Fred brings up the discussion on his future business plans, Janet disagrees with his request which leads an angry Fred while trying to get to his wife Janet, gets out of his car and steps in front of another fast moving one (driven by our third main lead named Al) having a near death experience. Later how these 3 characters meet under dire circumstances and what happens to them along the way constitutes the basic premise of this movie.
Talking about the visual imagery, this movie has got some great natural background settings which helps with our mood and our brain coming to terms with the fact that if anything were to happen to our main leads there's no one around to know on what exactly happened. And coming to one of our main leads Fred, his character is designed in such a way that he's really sharp and quick about his thoughts and actions. At times his actions seem to be dumb and we get the feeling that "Why did he have to do that!?" but trust me, he's miles ahead when compared to us when put in those situations that he's in. Though I was not rooting for him, I was really eager to find out what his next steps are going to be and how he's going to escape from those situations.
And here comes the best part of the movie, THE ENDING!! I mean, based on how the movie progressed you'll expect what the ending is going to be, but NO!, the director surprises us by having an ending which is close to reality and it looked so satisfying for me when compared to all the possible ordinary endings that I had in my mind during my watch. God! 70s period is like the rebirth of cinema, where people were so brave and not afraid to experiment.
