Some very good story lines often have some parts that do not make sense, as in the case of this movie you stated about the security of oil company.
The story seems interesting. The family story as well as the thoughts about climate change. The idea of a bacteria that eats oil can be a world changer if it would really come in reality. World without fossil fuel would be a great difficulty for the people of this century. Our living is dependent on the fuel. Can we imagine walking on carts again,and what about long distances. Difficult! very difficult!
