Attempts to move to Paris in the 1950s were unsuccessful, as her passport was revoked during that time, apparently in reaction to her left-wing political beliefs.

Margalit Fox of The New York Times described Replansky's poetry as "keenly celebrated yet curiously unheralded" for decades, suggesting that her spare style and reliance on rhyme was unfashionable to many poets and critics during the mid-20th century.

[1] However, as the years progressed, her writing was praised by David Ignatow, Marie Ponsot, Grace Paley, and Ursula K. Le Guin.

"[6] Booklist said of The Dangerous World, "with timeless grace, she sets each poem simmering with powerful phrasing and universal experience.... Replansky brings us ageless work in a collection that should not be missed.

"[7] Replansky's work was the subject of a lengthy article in the Los Angeles Review of Books, which cites United States Poet Laureate Philip Levine, "who once characterized Replansky as 'an intensely political poet, appalled by the cruelty, greed, and corruption of the masters of nations and corporations, appalled and enraged.'

Nevertheless, she mostly eschews the role of protest poet, opting instead to dramatize the intense vulnerability of individual human subjects in a verse style that is both delicate and tough-minded.... One lives with Replansky's poems instead of simply reading or hearing them, because they speak, with intensity and concision, to essential human concerns: the longing to belong and the concomitant ache of exclusion; rage against injustice; awareness of one's own vulnerabilities, particularly those that come with aging; and the profound joy at experiencing true fellowship with others or communion with oneself."

[10] In her later years, she lived on the Upper West Side of Manhattan with her Vienna-born wife, Eva Kollisch, an author and professor of comparative literature and women's studies at Sarah Lawrence College.
