Some, mostly fans, vociferously lament the changes, seeing Nancy as a silly, air-headed girl whose trivial adventures (discovering who squished the zucchini in 2004's "Without a Trace") "hold a shallow mirror to a pre-teen's world." Leona Fisher argues that the new series portrays an increasingly white River Heights, partially because "the clumsy first-person narrative voice makes it nearly impossible to interlace external authorial attitudes into the discourse", while it continues and worsens "the implicitly xenophobic cultural representations of racial, ethnic, and linguistic others" by introducing gratuitous speculations on characters' national and ethnic origins.
