SERIES PREMIERE: This newest FX series looks at the genesis in America of the crack epidemic, by focusing on a handful of characters who prove central to the drug’s importation and spread in Los Angeles in the early 1980s. Damson Idris, as the ambitious young kid who finds himself a major player, is at the center, and is an impressive find as a series lead. You care about him, as he navigates the streets, makes the deals, and suffers the setbacks related to the initial exponential spread of crack. But except for his Franklin Saint, a lot of Snowfall unfurls without being sufficiently involving. This series may grow on us in time – but the first episodes sent out for preview don’t exactly hit with blizzard force.
