Styna Chyn, from Film Threat, wrote: "Even though Jackie Chan did not direct "The Myth," (Stanley Tong), he did produce it; and his creative input echoes throughout this genre-bending action film. Shot in China, Hong Kong, and Hampi, India, "The Myth" is a comedy of epic proportions. Combining historical fantasy, martial arts, and science-fiction, Tong's film follows archaeologist Jack (Jackie Chan) and scientist William (Tony Leung Ka-Fai) on their adventures in investigating the veracity of a myth involving immortality, levitation, and a Korean princess-turned-concubine for Emperor Qin towards the end of the Qin Dynasty."
David Cornelius, from efilmcritic, gave the film 4 out of 5 stars and wrote: "Once again, it’s time to lament that while Jackie Chan has spent the past few years churning out mostly mediocre-or-worse flops like "Around the World in 80 Days" or those damn "Rush Hour" sequels in Hollywood, he's also spent the same time flying back home every now and then to make some darn-good-or-better flicks that, sadly, remain mostly unseen Stateside because they've been unceremoniously dumped onto DVD by the studios that pick up the rights to them but then never really bother to do anything about it."
Jim Hemphill, from Reel Films Reviews, gave the film 4 out of 5 stars and wrote a positive review: "Jackie Chan's The Myth is enjoyable but second-rate Jackie Chan, an action film that's completely satisfying on every level except when compared to the star's own best work. Chan has, in some ways, become a victim of his own excellence: the astonishing stunt work and action choreography of his peak years (the 1980s period of the Police Story and Project A films) have set up expectations that no performer could continue to live up to, certainly not after moving into middle age. Viewers weaned on Chan's classics will undoubtedly find The Myth to be Jackie-lite, a slightly slowed-down version of his usual acrobatics. Yet the film does contain a few superb set pieces reminiscent of vintage Chan, and director Stanley Tong's opulent visual style makes it a feast for the eyes—and the bottom line is that half-speed Jackie Chan is still more dynamic than just about any other action hero."
Robert Koehler of Variety wrote a generally negative review of the film: "Resembling a story session where many ideas are brainstormed and few stick, The Myth messily reps Jackie Chan in epic mode as a [contemporary] archaeologist drawn into a plot to plunder the treasure of the Qin Dynasty's first emperor. As part of a movement in H.K. cinema to return to the ambitious movies of yore, helmer Stanley Tong's multi-period adventure flirts with considerable entertainment on one hand and near self-destruction on the other. Whether Chan's star power will pull in enough international bizbiz is doubtful, though ancillary should flex muscles in most territories."
David Nusair, writing for Reel Film Reviews from the 2005 Toronto International Film Festival, was even less impressed: "That The Myth eventually turns into an almost interminable experience is a shame, given the light-hearted and genuinely entertaining vibe of the film's opening hour...Fortunately, The Myth contains several expectedly impressive action sequences – with a fight set within a rat paper factory an obvious highlight – although it's not long before such moments wear out their welcome. This is particularly true of an unbelievably tedious plot development towards the end, which finds all of the film's central characters forced to duke it out inside some kind of an infinite, gravity-defying mausoleum (!) Chan is reportedly looking to get away from some of the sillier films he's been churning out as of late, but The Myth certainly does not mark a step in the right direction".
