Name : Rafer Guzman / Alias : Newsday
A breezy, enjoyable comedy, and an ideal vehicle for the endearing McCarthy.

Name : Richard Roeper / Alias : Chicago Sun-Times
What does work, in every scene, is Melissa McCarthy's performance. She's as funny and as winning as anyone in the movies these days.

Name : A.O. Scott / Alias : New York Times
The busy, silly script allows Ms. McCarthy to be her own best sidekick, in effect an entire sketch-comedy troupe unto herself.

Name : Tom Long / Alias : Detroit News
McCarthy is not a one-size-fits-all talent; she needs the right vehicle. Here, Feig has given her precisely the right vehicle, and she shines.

Name : Michael Phillips / Alias : Chicago Tribune
The fun of "Spy" comes in watching the right actors mess with their own images, blithely.

Name : James Berardinelli / Alias : ReelViews
The characters are one-dimensional. The narrative is flat and obvious.

Name : Mick LaSalle / Alias : San Francisco Chronicle
Everyone involved seems to have had a good time with "Spy," and so will the audience.

Name : Wesley Morris / Alias : Grantland
In Spy, she's playing a caricature that is almost a complete character. The movie isn't out to humiliate her. It wants to prop up a version of heroism that makes sense for McCarthy.

Name : Liam Lacey / Alias : Globe and Mail
Although this fish-out-of-water scenario might sound over-familiar, both the humour and action here are startling and visceral .

Name : Andrew O'Hehir / Alias : Salon.com
McCarthy has much more to discover about herself as an actor and an avatar and a cultural signifier, and I hope she doesn't get trapped by one role, one genre or one franchise. But her campaign of conquest is going well.

Name : Ann Hornaday / Alias : Washington Post
Feig's movies aren't particularly stylish - the visuals in "Spy" are serviceable at best, and the makeup is particularly un-subtle - but they possess a silly, sweet streak that makes them irresistibly infectious.

Name : Richard Brody / Alias : New Yorker
Melissa McCarthy shines in this clever action-comedy showcase provided by the writer and director Paul Feig, but the movie's tightly contrived plot and uniformly positive emotions constrain her comic genius.

Name : Peter Travers / Alias : Rolling Stone
McCarthy and director Paul Feig, are a dynamite team, with Feig's script a bonanza of zingers and femcentric subtext.

Name : Amy Nicholson / Alias : L.A. Weekly
Spy is a call to arms for the cowed, and a riotous skewering of the workplace kings

Name : Peter Howell / Alias : Toronto Star
One part parody, one part thriller, one part lethal satire of movie sexism.

Name : Stephen Whitty / Alias : Newark Star-Ledger
[It] does have its moments, and it does have McCarthy. And while it's not worth much more than a rent, it does make us look forward to what she's going to do with "Ghostbusters."

Name : Bob Mondello / Alias : NPR
Feig's cheerfully feminist script makes only as much sense as it absolutely must, while providing McCarthy with chances to crack wise, show vulnerability and class, and do some of the more elegant pratfalls you'll have seen in a while.

Name : Moira MacDonald / Alias : Seattle Times
"Spy," plus popcorn, feels just right.

Name : Justin Chang / Alias : Variety
Melissa McCarthy gets the funniest, most versatile and sustained comic showcase of her movie career in this deliriously entertaining action-comedy.

Name : Jake Coyle / Alias : Associated Press
It's a globe-trotting tour of McCarthy's talent, throughout which she's practically always kicking butt. Who was that double-O-what's-his-face, anyway?

Name : Kyle Smith / Alias : New York Post
If they do a sequel (teased in the final seconds), they should cut down on the endless, tedious chases and shootouts.

Name : Chris Nashawaty / Alias : Entertainment Weekly
Put the woman in any damn thing she pleases. She's that good.

Name : Colin Covert / Alias : Minneapolis Star Tribune
It's as if writer/director Paul Feig studied an Ian Fleming list of everything you're not supposed to do in a spy yarn, then did it all - thereby producing an excellent adventure movie so funny you can barely catch your breath between scenes.

Name : Steven Rea / Alias : Philadelphia Inquirer
If a Spy sequel isn't already in the works, they better get cracking. Nefarious terrorists and numskull guys await.

Name : J. R. Jones / Alias : Chicago Reader
Hollywood is gradually figuring out what to do with Melissa McCarthy.

Name : Joe Neumaier / Alias : New York Daily News
The intel is in: Melissa McCarthy can carry a comedy. Specifically, "Spy."

Name : Randy Myers / Alias : San Jose Mercury News
Feig draws out McCarthy's best, and she's up to the challenge, whether it's expressing tenderness and anger or slapsticking her way through the physical humor.

Name : Mark Olsen / Alias : Los Angeles Times
"Spy" may not be a great movie, but it is great fun. And at times it will have you wondering if there's that much of a difference.

Name : Alonso Duralde / Alias : TheWrap
McCarthy and Byrne's scenes together are cruelly hilarious, with the kind of no-holds-barred insult humor that makes you instinctively drop your jaw and cover your mouth.

Name : Andrew Lapin / Alias : NPR
Spy is actually quite funny. It even proves itself to be in the same league with the first two films in Feig's loose comic trilogy, Bridesmaids and The Heat .

Name : Bill Goodykoontz / Alias : Arizona Republic
Finally, after the promise shown in "Bridesmaids" but sold short since by weak scripts in films like "Tammy" and "Identity Thief," Melissa McCarthy gets a movie vehicle worthy of her talents.

Name : Jesse Hassenger / Alias : AV Club
Rare is the broad mainstream comedy that can goof on its bigger-budget Hollywood siblings while providing a few moments of sincere uplift.

Name : John DeFore / Alias : Hollywood Reporter
Melissa McCarthy comes into her own as a comic star in Spy, stepping out from recent supporting- and co-headlining roles to become the big screen A-lister she promised to be in 2011's Bridesmaids.

Name : David Edelstein / Alias : New York Magazine/Vulture
Feig keeps throwing so much stuff at you - gross-out gags, chases, brutal violence, not to mention actors working their heads off - that he finally wears down your resistance.

Name : David Ehrlich / Alias : Time Out
The tricksy plot allows McCarthy to explore the full range of her comic persona, and Feig is smart enough to get out of her way as the mild-mannered Susan starts wielding f-bombs as comfortably as Bond whips around a Walther PPK.

Name : Dana Stevens / Alias : Slate
Spy lampoons sexism without abandoning sex-a tough tone for a comedy to strike but one that Feig and McCarthy manage to accomplish with both a sense of justice and a sense of humor.

Name : Tom Russo / Alias : Boston Globe
Melissa McCarthy doesn't just adopt guises to fool the bad guys in "Spy." Part of what makes the action comedy such a loopy blast is the identity shifts she pulls on the audience.

Name : Joe Williams / Alias : St. Louis Post-Dispatch
With the overlong, limp and lazy "Spy," Feig has lost his mojo.
