In the twenty-first century, Pippi has continued to maintain her popularity, often placing on lists of favorite characters from children's literature or feminist characters. She is regarded as the most well-known of Lindgren's creations, and appears as a character in Astrid Lindgren's World, a theme park in Vimmerby, Sweden, dedicated to Lindgren's works, and on the obverse of the Swedish 20 kronor note, as issued by Riksbank. Additionally, Pika's Festival, a children's festival in Slovenia, borrows its name from her. Pippi has also inspired other literary creations: for his character Lisbeth Salander in the "Millennium" series, Stieg Larsson was inspired by his idea of what Pippi might have been like as an adult. Pippi has continued to remain popular with critics, who often cite her freedom as part of her appeal. "The Independent"s Paul Binding described her as "not simply a girl boldly doing boys' things," but rather "n her panache and inventiveness she appeals to the longings, the secret psychic demands of girls and boys, and indeed has happily united them in readership all over the world." Susanna Forest of "The Telegraph" called Pippi "still outrageous and contemporary" and "the ultimate imaginary friend to run along rooftops and beat up the bad guys." In "100 Best Books for Children", Anita Silvey praised the character as "the perfect fantasy heroine — one who lives without supervision but with endless money to execute her schemes."
