The chemistry between Bullock and McCarthy is what brings the screen to life. McCarthy steals the show and gets the maximum laughs for her shrewd performance.
Bullock on the other hand, with her restrained onscreen personality, is used as a foil character that ups McCarthy's presence. All the others in the cast, though they performed well, were only doing their part. None had "their" moment of glory.
Kattie Dippold's script is lukewarm and does not gather momentum to give a boiling point. The dialogues are staid. The gags, especially the Mullins' family get-together scene seemed very obligatory and forced, so did the escapade hungama.
Coming from director Paul Feig, who had previously given us the fabulous Oscar nominated "Bridesmaids", "The Heat", with its odd-couple-cops and a vague drug-bust plot, is a big letdown.
