Fonda is terrific playing the mess that is Viola. Her introduction tells you everything you need to know about her: after learning she has been fired she attacks a vacuous Britney Spears clone on air. It never reaches that kind of mean-spirited fun again.
For a revenge comedy to work, the villain should be so despicable that you relish those moments when the victim turns the tables and gets even. This flick is misleading because the title character is not really mean, but rather a sympathetic figure.
