[26] Mariel Concepcion of Billboard noted "Breaking Point" as a "reminiscent of Melanie Fiona's "Give It to Me Right" and Beyoncé's "Why Don't You Love Me".

[32] According to Matthew Horton of BBC Online, Hilson's smooth vocals on "Beautiful Mistake", takes you back to Michael Jackson's Thriller album.

[33] On the other hand, "Gimme What I Want" has been described as an "electro anthem",[22] and according to Andy Kellman of Allmusic, the song is part two to both "Turnin Me On" and "Get Your Money Up".

[19] Ben Ratliff of The New York Times wrote that "Hilson gets a certain energy out of bossiness", but expressed a mixed response towards its production and viewed that the album lacks a "narrative".

[23] Slant Magazine's Eric Henderson gave it two-and-a-half out of five stars and commented that Hilson "misses the independence espoused by everywomen Khan and Houston and essentially says 'That's a good idea' to her reverse harem of producer-songwriters".

[31] Los Angeles Times writer Margaret Wappler commented that Hilson "is concerned with boundaries" and stated "nearly every song is cluttered with as much textural filigree as possible to distract from the absence of narcotic radio hooks".

[86] Caroline Sullivan of The Guardian noted its "conventional sex-and-love piffle" and wrote that the album "is muddled and devoid of the gutsiness the title leads us to".

[18] USA Today's Elysa Gardner gave the album two-and-a-half out of four stars and noted "how little of her own voice comes through on this set of smart and pleasurable but mostly disposable pop-soul candy".

[20] BBC Online's Matthew Horton found its music less "ordinary" than that of her previous album and commented that "Hilson is in warm, confident voice throughout".

[33] Ken Capobianco of The Boston Globe complimented the songs concerning "finger-wagging affirmations of self", but wrote that "she never maintains this strong sense of purpose.
