3.5 stars out of 4 -- "[A] terrific Western, a potently acted powerhouse that sticks in the mind and the heart....There is nothing abstract about Harris' approach to APPALOOSA. Every frame of the movie indicates his bone-deep respect for classic film Westerns..."
Rolling Stone "[I]n Harris and costar Viggo Mortensen, it has two actors who beautifully play the kind of tough, laconic, unflappable men Westerns could not exist without."
Los Angeles Times "The dialogue, based on Robert B. Parker's novel and co-written by director and star Ed Harris, is a major asset....The movie's undeniable highlight is the chemistry between Harris and Viggo Mortenson..."
USA Today "Mr. Harris can be an imposingly serious actor...but there is often a saving glint of mischief in his eye. And in APPALOOSA, his second feature as director, he leavens the atmosphere of costumed rigidity and somber stoicism with sly, relaxed humor."
New York Times "Irons is enjoyable nasty, enough to make you wonder why no one thought to cast him in a Western before."
Entertainment Weekly 3 stars out of 5 -- "Ed Harris is the latest to Hollywood player to tackle the western genre....The laid-back lawmen supply the main pleasures..."
Total Film 3 stars out of 5 -- "[T]he film sets about a gutsy collection of brawls, gunfights and getaways to spell out its celebration of John Ford's tall tales..."
