I disagree with that mainly because she was one of the film's very, very few woman characters. (With lines!) Since there are so few women, the roles each play are more important than they would be if the movie had a surplus of female characters. So, if they'd had a few more female cops, or some female politicians that didn't get killed and got more lines, or hell, some female mobsters? I'd have been golden. But since we had about four women, the traitor girl cop stuck out more.
