One of my favourite films is Nancy Drew (2007). I love this film because it's kind of a detective. I love mysteries (I can't say it often enough) so this is a very perfect film, especially because Nancy always wears something vintage, or vintage-like. I also really love Ned, her best friend.
Emma Roberts is very good as Nancy!
Nancy Drew is one of the most popular detectives. People have been writing about her for many decades, making sure she's up to date. I love watching the old Nancy Drew series, with The Hardy Boys which you can find here.
