In 1950, "Pippi Longstocking" was translated into American English by Viking Books, featuring Louis Glanzman's artwork. It did not become a bestseller, although sales did eventually improve after the initial release; more than five million copies had been sold by 2000. Pippi was positively received by American reviewers, who did not find her behavior "subversive" or problematic, but rather "harmless" and entertaining. Eva-Maria Metcalf has argued that Pippi was subject to a "double distancing" as both a foreign character and one believed to nonsensical, thus minimizing her potentially subversive actions that had stirred the minor controversy earlier in Sweden. As a result of Pippi and Lindgren's growing recognition in the United States, Pippi's behavior in later books became more critically scrutinized by literary critics, some of whom were less sure of the "hilarious nonsensical behavior, the goodness of her heart, and the freedom of her spirit" that had been lauded in earlier reviews. Reviewers of "Pippi in the South Seas" in "Hornbook" and "The Saturday Review" found Pippi to be less charming than in earlier books, with "The Saturday Review" describing her as "noisy and rude and unfunny."
