My review was written in May 1981 after a Greenwich Village screening:
"Subway Riders" is an atmospheric feature, which in its stylistic fashion accurately captures the feeling of big-city anomie today with a nod to the cine-noir approach of the 1940s. Filmmaker Amos Poe demonstrates a flair for sustained mood and expressive dialog, but at nearly two hours pic is overlong.
Melodramatic tale focuses on a street-corner alto sax player, who takes to shooting down his listeners at night. Fragmented subplots deal with the tough and cynical cop tracking him down, the cop's' strange drug-addicted, a nasty prostitute neighbor of the sax man and her girlfriend, and a mysterious blonde (with young daughter) who weaves in and out of the other characters' stories.
Picture sustains a mood of despair, but is laced with black humor. Lengthy monologs hold one's attention at first due to flavorful writing, but ultimately become wearying in later reels. The sax player is played by both John Lurie and director Poe in different scenes, a ploy that fails in the contrast between Lurie's credibility with his ax and Poe's no-fingering mime.
Supporting cast is effective, with an arresting, uninhibited turn as the junkie wife by Susan Tyrrell. Both she and director Poe deserve credit that name thesp blends comfortably into an "underground" ensemble.
Johanna Heer's neon-lit interiors are quite striking, but film's technical credits generally reflect its extremely low budget. Commercial chances seem limited to midnight and campus dates.
