Decentman wasn't to decent with his review, I will try to dispel the rumor, that this was poorly written.
Snowfall began by showing the disconnect between the have and have-nots, and the solutions provided to close that gap. Reality can be very ugly, and be the basis for an ugly truth, that crack/cocaine stole the hopes and dreams of a society.
The landscapes where most of the events take place, are not stylized and cocaine use was not sensationalized. The character development, supplied in this pilot, prepares us for the horrific ride we are about to embark.
The writing was a mirror reflection of those turbulent times.
