The Nancy Drew character of the "Files" series has earned mixed reviews among fans. Some contend that Nancy's character becomes "more like Mildred Wirt Benson's original heroine than any since 1956." Others criticize the series for its increasing incorporation of romance and "[dilution of pre-feminist ." One reviewer noticed "Millie Wirt Benson purists tend to look askance upon the "Files" series, in which fleeting pecks bestowed on Nancy by her longtime steady, Ned Nickerson, give way to lingering embraces in a Jacuzzi." Cover art for "Files" titles, such as "Hit and Run Holiday" (1986), reflects these changes; Nancy is often dressed provocatively, in short skirts, shirts that reveal her stomach or cleavage, or a bathing suit. She is often pictured with an attentive, handsome male in the background, and frequently appears aware of and interested in that male. Nancy also becomes more vulnerable, being often chloroformed into unconsciousness, or defenseless against chokeholds. The books place more emphasis on violence and character relationships, with Nancy Drew and Ned Nickerson becoming a more on-off couple, and both having other love interests that can span multiple books.
