this documentary be my first introduction to peak oil theory . a fascinating concept that have a lot of frighten consequence if it turn out to be correct . i have absolutely no idea that the effect of oil depletion would come so soon and it literally take my breath away . this movie will probably open your eye a to how strongly the american way of life be dependent on the abundance of cheap oil a term use throughout the film . a lot of the topic be plain common sense and and they do not go into a huge amount of depth about any of them . but you have probably never put all the piece together like this movie do . the interview with the author and energy expert be all very interesting . i do not think this film be mean to scare people . it merely mean to inform people about what to expect in the year ahead and and maybe to encourage you to think twice about commute 100miles to work and leave your light on all day long . after watch this film i be no longer able to look at the car and bus zoom by quite the same . great documentary and everyone should see it .
