"The killing of the Black Panther leader Fred Hampton gives rise to a generic psychological thriller."The peculiarity of “Judas and the Black Messiah,” the new film about the betrayal that led to the murder of the Black Panther Party leader Fred Hampton, in 1969, is that (as has often been said of “Paradise Lost”) the Devil gets the best lines. The movie, directed by Shaka King (who co-wrote the script with Will Berson), doesn’t suggest that there’s any allure in betrayal; it simply makes the betrayer’s story more interesting, and thus falls prey to a dramatic mechanism that’s been more or less a constant throughout film history.
