Glenn Lovell, San Jose Mercury News: A joltin' powerhouse of a movie that deals more in fleeting impressions than pat answers. Read more
Terry Lawson, Detroit Free Press: Intelligent, exquisitely acted though ultimately unengaging. Read more
Richard Roeper, Ebert & Roeper: It's good -- but Ali himself was the greatest. So a reluctant, kind of mild thumbs up for this. Read more
Kenneth Turan, Los Angeles Times: Quite accomplished but finally distant. Read more
Moira MacDonald, Seattle Times: Smith ... demonstrates not only impressive boxing prowess ... but a maturity and subtlety that he's never before shown on screen. Read more
Chris Vognar, Dallas Morning News: Loaded with bravura filmmaking flourishes, and exceptional performances. Read more
Mark Caro, Chicago Tribune: We've seen Ali as the charismatic star of the real-time drama of his life. Ali, for all its flashy filmmaking, just doesn't compare. Read more
Elvis Mitchell, New York Times: Mann's first movie with feeling; his overwhelming love of its subject will turn audiences into exuberant, thrilled fight crowds. Read more
Gene Seymour, Newsday: The most impressive and persuasive rendering of a late-20th-century icon since Anthony Hopkins turned on that old Nixon charm in Oliver Stone's 1995 biopic. Read more
Eleanor Ringel Gillespie, Atlanta Journal-Constitution: Very good and definitely worth seeing, if only to be reminded of the extraordinary life of one of the most extraordinary figures of the last half of the 20th century. Read more
Eric Harrison, Houston Chronicle: It's stirring to be reminded of what a glorious and galvanizing figure Ali was. Read more
Paul Tatara, CNN.com: If you have any interest at all in the subject, Ali is worth your time. Read more
Steven Rosen, Denver Post: It does connect solidly more often than not. Read more
Owen Gleiberman, Entertainment Weekly: Dazzling, flawed, achingly ambitious. Read more
Rick Groen, Globe and Mail: [Mann] manages to dissect the sport visually, transcending the brutality cliche to reveal how speed and power and courage combine with fatigue and desperation and fear. Read more
Ella Taylor, L.A. Weekly: The film gives Ali his due by refusing to idealize him or to gloss over his failings. Read more
Peter Rainer, New York Magazine/Vulture: Ali is a far more complex creature than this movie allows for. Read more
Rex Reed, New York Observer: It is well-intentioned, sketchy, sprawling and unremarkable. At two hours and 38 minutes, it is also long-winded and exhausting. Read more
James Berardinelli, ReelViews: Even though the movie is too long and suffers from an inconsistent tone, the narrative is compelling, as are the performances. Read more
Roger Ebert, Chicago Sun-Times: It lacks much of the flash, fire and humor of Muhammad Ali and is shot more in the tone of a eulogy than a celebration. Read more
Charles Taylor, Salon.com: This could be the only movie we'll get on the fighter, and it's just not good enough. Read more
Bob Graham, San Francisco Chronicle: If Michael Mann's new biopic of Muhammad Ali is not right up there with the gold standard of boxing biographies, Martin Scorsese and Robert De Niro's Raging Bull, it misses by only a whisker. Read more
Colin Covert, Minneapolis Star Tribune: Read more
Geoff Pevere, Toronto Star: A movie that, at its best, is as brashly eloquent in cinematic expression as Ali was with his fists. Read more
Mike Clark, USA Today: Ali is no disgrace, but it's not much of a performer, especially considering that it is one of the few hyped year-end releases that coulda been a contender. Read more
J. Hoberman, Village Voice: Filled with vivid cameos and set to an infectious soul beat that effectively covers the underlying hum of calculated precision. Read more
