The reviews of The Heat focus mostly on the two stars, Sandra Bullock and Melissa McCarthy. The two play police officers -- one uptight and conservative and the other, well, she's played by McCarthy. Bullock can do a double-takes better than any actress working today, writes Lou Lumenick in the New York Post, and boy, does force-of-nature McCarthy give her plenty to work with. Betsy Sharkey in the Los Angeles Times agrees. McCarthy and Bullock are an odd and oddly likable team, she comments. Both actresses are fearless with physical comedy. Rafer GuzmÃ¡n in Newsday dismisses the script as skimpy but adds that it's a sturdy skeleton for the real meat, which is our heroines' budding Friendship. That's a conclusion that several other critics have reached, including The New York Times's A.O. Scott. The volatile chemistry between Ms. McCarthy and Ms. Bullock is something to behold, and carries The Heat through its lazy conception and slapdash execution, he writes. Several other critics, however, are not willing to forgive the filmmakers for the meager plot so readily. Teaming Sandra Bullock and Melissa McCarthy for a good cop/bad cop comedy is a no-brainer, comments Peter Howell in the Toronto Star. Regrettably, 'no-brainer' also describes the weak script. Joe Morgenstern in the Wall Street Journal calls it crude and clearly commercial. But Ty Burr in the Boston Globe remarks, If you're going to make a dopey, foul-mouthed, predictable lady-buddy-cop movie, you might as well make it funny. And until it overstays its welcome in the final half hour, The Heat is shamefully funny.
