PRO:
In what has been a pretty remarkable career up to now, it's this performance that fully affirms Smith as one of the great leading men of his generation. -- Scott Foundas, Village Voice
The Manhattan movie of the year, Francis Lawrence's I Am Legend, offers a stunning glimpse into how the city - as we know it today - might look in 2012 if it were abandoned in 2009. -- Jack Mathews, New York Daily News
The first two thirds and change of I Am Legend is terrific mindless fun: crackerjack action with gnashing vampires barely glimpsed (and scarier for that) and how'd-they-do-that New York locations that retroactively justify the traffic jams. -- David Edelstein, New York Magazine
A scary, inventive, exciting and breathless adventure that combines the best elements of Children of Men, Escape from New York and The Road Warrior, but leaves out the worst stuff - such as the story-clogging despair and political allegory in Children, a movie that made apocalypse look like kind of a downer. -- Kyle Smith, New York Post
The movie year's most expensive and ambitious sci-fi spectacular, I Am Legend, is three movies in one: a futuristic effects-o-rama, a zombie thriller and a survivalist parable. Each is better than average, and the experience is fairly gripping. -- William Arnold, Seattle Post-Intelligencer
MIXED:
The movies being sold as a high-octane action spectacular, but thanks to Smith and Lawrences directorial restraint, the quiet moments are what define the film, and what you find yourself wanting to see most. If anything, its the action scenes that fail. -- Peter Suderman, National Review
In spirit, I Am Legend is caught in some abstractly doom-laden sci-fi past. For what it is, though, the film is well-done, a case of suspenseful competence trumping questionable relevance. -- Owen Gleiberman, Entertainment Weekly
The first two-thirds are classic science fiction, technologically plausible and emotionally resonant. It's only when God enters the picture that things slide downhill. -- Lawrence Toppman, Charlotte Observer
There is something a bit thin about the story, and just as in 28 Days Later, I find that digital, rage-filled zombies halve in dramatic interest with every second that passes. There's a credibility niggle too: in this post-apocalyptic wasteland, Neville's apartment has electricity, perhaps from a generator - but also running water. No one, though, could fail to be impressed by the gobsmacking digital creations of an empty, ruined Manhattan, a jungle with real zoo-bred animals roaming around. -- Peter Bradshaw, Guardian
The vision of a Manhattan filled with abandoned cars, its bridges shattered, lions chasing deer down Fifth Avenue, Times Square overgrown with rushes, is poetically realised by production designer Naomi Shohan and probably accounted for a large part of the fabulous budget. Smith, alone with his dog for much of the time, commands our attention as the resourceful Crusoe figure, and there are some good action set pieces as Neville does battle with the ghastly mutants. But despite a tagged-on happy ending, this is a deeply depressing experience as no doubt Matheson intended it to be back in the angst-ridden Fifties. -- Philip French, Observer
The movie works well while it's running, although it raises questions that later only mutate in our minds. -- Roger Ebert, Chicago Sun-Times
Remarkably eerie yet annoyingly larded with cheap horror-film shock effects, I Am Legend stands as an effective but also irksome adaptation of Richard Matheson's classic 1954 sci-fi novel. -- Variety
Some cartoonish CGI and a mangled screenplay that misses the novel's point are downsides but the apocalyptic vision brings definite chills. -- Jamie Russell, bbc.co.uk
Overall, I Am Legend is a wasted opportunity - a rickety, weather-beaten framework around an otherwise strong central performance from Smith. -- Eric Alt, Premiere
CON:
Science fiction fans hoping for a faithful adaptation of Matheson's novel will be disappointed. This is no more a visitation of the source material than its predecessors, The Last Man on Earth or The Omega Man, were. -- James Berardenelli, ReelViews
This new version of I am Legend completely perverts the meaning of the title, losing the clever, dark irony and turning it instead into something heroic rather than something tragic. -- Beth Accomando, kpbs.org
Matheson's bitterly ironic ending - which pivots on the nature of Neville's legend - is gutted and turned into formulaic pap. -- Maitland McDonagh, TV Guide
After its promising opening, I Am Legend devolves into a generic zombie slaughterfest. -- Liam Lacey, Globe and Mail
A big part of the reason for this movie's nose dive around the one-hour mark is that, seen up close, the Infected just aren't that scary. -- Dana Stevens, Slate
The credits list a couple of dozen medical and scientific consultants. What this film really needed was a script doctor. -- Michael Sragow, Baltimore Sun
Unfortunately, after those first 10 minutes its all downhill for I Am Legend, as the film descends into a monster-movie malaise starring a horde of balding CGI monsters that look like refugees from a video game and that will scare absolutely no one, save those who worry that green-screening is ruining the movies. -- Josh Rosenblatt, Austin Chronicle
