Name : Alonso Duralde / Alias : TheWrap
It's not going to make anyone forget Jaws, but it delivers the kind of breathless tension that justifies its existence.

Name : Tom Russo / Alias : Boston Globe
Yes, there's shameless bikini ogling, but what could have been throwaway exploitation is instead a frequently gripping portrait of dire-straits resourcefulness.

Name : Michael O'Sullivan / Alias : Washington Post
Is "The Shallows" a thriller for the ages? No, but it's decent popcorn fare.

Name : Ignatiy Vishnevetsky / Alias : AV Club
A fitfully entertaining mix of offscreen gore and Maxim-esque T&A.

Name : Andrea Gronvall / Alias : Chicago Reader
This is silly stuff but often genuinely scary, with excellent aerial and undersea photography and some persuasive special effects.

Name : Richard Roeper / Alias : Chicago Sun-Times
The Shallows is a great-looking film, peppered with overhead long shots of the amazingly clear water, and some terrific underwater photography as well.

Name : James Berardinelli / Alias : ReelViews
The Shallows is almost a good movie.

Name : Adam Graham / Alias : Detroit News
For what it is, "The Shallows" works.

Name : Edward Douglas / Alias : New York Daily News
The Shallows isn't bad as much-needed escapist summer fun

Name : Peter Debruge / Alias : Variety
Lively may have been cast primarily for her physique, but she proves a compelling heroine all the same.

Name : Glenn Kenny / Alias : New York Times
[Lively] acquits herself well here, especially in the vulnerable-to-shark-attack department.

Name : Peter Howell / Alias : Toronto Star
The Shallows pushes the buttons it's supposed to push for a summerthriller, even if the outcome is as deflating as it dumb.

Name : Kyle Smith / Alias : New York Post
The girl kept talking and strategizing as heavy string music played on the soundtrack.

Name : Stephen Whitty / Alias : Newark Star-Ledger
Lively can act, and she does a good job with a very difficult role here - holding our interest and sympathy for a feature-length movie with no one to talk to for most of it.

Name : Matthew Lickona / Alias : San Diego Reader
The progression from personal drama to surf film to (wo)man vs. nature story to full-on creature feature is smooth, even expert, and always managed with handsome panache.

Name : Joshua Rothkopf / Alias : Time Out
You're gonna need a bigger Blake (and you're going to get one) in Lively's enjoyably trashy shark-survival movie, the definition of summer fun.

Name : Peter Travers / Alias : Rolling Stone
It's all patently ridiculous. But Blake Lively, director Collet-Serra and a digital shark show no mercy in hooking us with the B-movie tension. And we bite.

Name : Michael Phillips / Alias : Chicago Tribune
If the amount of surfing/suffering/staring-at-dark-skies footage rendered in slow motion were depicted at normal speed, "The Shallows" would run about a minute and a half.

Name : Chris Klimek / Alias : NPR
The Shallows is a thoroughly mediocre specimen of the externalized-grief survival flick, distinguished by a strong performance from Gossip Girl alumnus Lively.

Name : Peter Hartlaub / Alias : San Francisco Chronicle
The most important parts, the ones involving the shark, don't feel genuine.

Name : Chris Nashawaty / Alias : Entertainment Weekly
Clocking in at a svelte 87 minutes, the film knows its audience and the limits of that audience's patience with fare like this.

Name : Rafer Guzman / Alias : Newsday
A snack-size thriller that isn't quite enough to satisfy.

Name : Brad Wheeler / Alias : Globe and Mail
School's out, schlock's in - no lessons here.

Name : Liz Braun / Alias : Toronto Sun
The Shallows is brisk and engaging, and a great vehicle for Lively. The film has the sort of breathtaking cinematography that will inspire you to visit the ocean. And a story that may stop you from ever going into the water again.

Name : Bill Goodykoontz / Alias : Arizona Republic
We're gonna need a bigger boat?" "We're gonna need a smaller bikini," more like.

Name : Justin Chang / Alias : Los Angeles Times
If you're looking for a quick and satisfying summer thrill - a reminder that all you really need to make a movie is a girl and a flare gun - then the aptly titled Blake Lively-vs.-shark thriller "The Shallows" should serve you nicely.

Name : Christy Lemire / Alias : RogerEbert.com
The movie as a whole is such an incompetent train wreck, you can't look away, just to see how much worse it can get.

Name : Keith Uhlich / Alias : Hollywood Reporter
Wrongheaded, utterly incompetent, and nearly laugh-free .

Name : Jesse Hassenger / Alias : AV Club
A tortured use of another movie's absurd mythology to help make muddled quasi-satirical points, while indulging the apparently fail-safe punchline of saying the word "purge" about once a minute.
