Chicago Reader review:
Martin Scorsese transforms a debilitating convention of 80s comedy—absurd underreaction to increasingly bizarre and threatening situations—into a rich, wincingly funny metaphysical farce. A lonely computer programmer (Griffin Dunne) is lured from the workday security of midtown Manhattan to an expressionistic late-night SoHo by the vague promise of casual sex with a mysterious blonde (Rosanna Arquette). But she turns out to be a sinister kook whose erratic behavior plunges Dunne into a series of increasingly strange, devastating incidents, including encounters with three more treacherous blondes (Verna Bloom, Teri Garr, and Catherine O'Hara) and culminating in a run-in with a bloodthirsty mob of vigilantes led by a Mr. Softee truck. Scorsese's orchestration of thematic development, narrative structure, and visual style is stunning in its detail and fullness; this 1985 feature reestablished him as one of the very few contemporary masters of filmmaking.
Here (and above) is the trailer.
