Salon by Andrew O'Hehir

A stylish and muscular thriller with some nifty twists and turns, a wicked sense of humor, several terrific performances and not one or even two but three of the best car chases in recent action-flick history.

Unknown is finely tuned pulp filmmaking, a dumb movie with a smart veneer, which is nothing to sneeze at.

Chicago Tribune by Michael Phillips

Sleek and, until a stupidly violent climax, very entertaining, Unknown is the opposite of "Memento."

Philadelphia Inquirer by Steven Rea

It's all very Hitchcockian, at least for a while. And clever and exciting, too, even if the convergences begin to strain credulity, and, when you think about it, defy logic, too.

Washington Post by Ann Hornaday

The weakest link in Unknown - okay, other than the utter preposterousness of its entire premise - is Jones, who as a modern-day version of Hitch's ice queens can't hold her own with the likes of Kim Novak, Grace Kelly and Eva Marie Saint.

San Francisco Chronicle by Mick LaSalle

Neeson has a way of getting upset - a frantic purposefulness - that fills viewers with both empathy and anticipation: He's so miserable that we care.

Portland Oregonian by M. E. Russell

It works as designed.

New York Post by Lou Lumenick

Unknown actually has enough of a sense of humor to admit what it is: hybrid corn. But it's been crossbred from Hitchcockian stock.

The Hollywood Reporter

Director Jaume Collet-Serra provides a steady flow of suspense and a very Polanski-esque feeling of paranoia.

Boxoffice Magazine by Amy Nicholson

Jones delivers her line readings so robotically that even her truths sound like lies. She's got the look of a Hitchcock blonde, and the movements of a deer in the headlights. Even her kisses look fake.

Miami Herald by Connie Ogle

Unknown is never boring, and Collet-Serra mostly keeps up a lively pace, but he doesn't do the movie any favors with the flat, dull way he films the scene in which we finally learn what's going on.

Time Out by Joshua Rothkopf

Unknown is probably the movie "The Tourist" wanted to be, if it had a pulse. Its sheer momentum makes Neeson and Kruger more attractive than even Johnny Depp and Angelina Jolie.

Entertainment Weekly by Lisa Schwarzbaum

The movie whips up a big old puree of ingredients borrowed from other cinematic recipes.

Orlando Sentinel by Roger Moore

It's a solid, engrossing thriller, but a slack one.

Variety by Justin Chang

Beyond the occasional plot frissons and juicy supporting turns, it's an emotionally and psychologically threadbare exercise.

Village Voice by Nick Schager

As with its protagonist, Unknown boasts tantalizing issues buried deep beneath its frantic exterior, but little idea how to unlock or address them.

Arizona Republic by Bill Goodykoontz

There are a couple of intriguing ideas floating around here and there, but that's all they do - float around, unmoored by any sense of reality and, thus, suspense.

Observer by Rex Reed

Unknown makes no sense at all, so you not only worry about Liam Neeson's judgment in movies, but you begin to wonder if he's forgotten how to read.
