The dialogue is blunt, and the plot overly centers white heroism; but the period detail is well-observed, and the filmmakers show a real understanding of the ingrained attitudes and anxieties that make moments of social progress so difficult.
A good cast and the best of intentions cannot save the 1970s Boston school busing melodrama The Walk from its excesses. Funereal pacing, characters that are simplistic “types” and dialogue that recycles cliches and bromides pretty much overwhelm it.
