Soylent Green. 7/10.
Decent movie from 1973. Another one of those weird takes on the future. The year is 2012 and the earth is overpopulated. Greenhouse effect means there's hardly any crops. People eat synthetic food. Then a rich guy gets murdered for suspicious reasons...
The main character makes the whole movie. He's a cop who takes part of the scene of the crime with him. Liquor, real soap, vegetables... He's from the time where police still punched bad guys until they started talking.
