Slant Magazine describes it as "an undeniably quaint and self-fulfillingly naughty sex romp, shows a marriage entering its seven year itch ahead of schedule." Time Out says,
what really distinguishes the film is its wealth of poetic detail (merging raindrops, charging trains), and its bold, frank eroticism, most notably in the opening sequence of the girl's sexual initiation, with its luminous whites and ecstatic throes set almost in abstraction from her world hitherto.
