As entertainment, Nicotina manages a bracing balance. It arrests with violent bursts and anxious pauses until its three plots merge in a satisfying resolution; its laughs caught in my throat like smoker's cough.
Nicotina's every loser, criminal, dreamer, crank and cynic is flawed, but their flaws are primal and as human as thumbs. In the end, it's this grim but tender view of humanity that gives the movie its appealing combination of mordant humor and cheerful pessimism.
It seems likely that how much you enjoy Nicotina will be tied to how much you enjoyed the Guy Ritchie pictures it strongly resembles. Those who thought Lock, Stock, and Two Smoking Barrels and Snatch were the cats p.j.'s will likely enjoy Nicotina.
