“Dead End” (*1/2 out of four) was an aptly titled misfire set in L.A. as a young couple (Daran Acevedo and Sierra Collins) try to escape the cycle of drugs, crime, and violence that have entrapped them for years but find that leaving this life is much more fierce and difficult than they imagined. Promising opening about the drug trade and its effects on society proves to be a dead end in itself, as film becomes a by-the-numbers underworld story with unlikeable characters. Vivica Fox is top-billed but is only in the movie for a few scenes; clunkers like this make you wish someone would “set it off” for her and finally reignite her career.
