The movie was not screened for critics before its official release, and so far, the reviews that have been posted have been lukewarm.
David Voigt of Examiner.com said the movie has its entertaining moments but falls flat at other times.
"Hardly a movie that will ever run the risk of being taken with a completely straight face, this... is a film that has some fun gonzo moments appropriate with the genre, but ones that are also fairly restrained and doesn't do nearly far enough," Voigt wrote. "Heavy on the effects and the set pieces, it moves along at a fair enough pace but there are longs stretches where the film feels re-written and often drab."
The Hollywood Reporter's Stephen Farber said the movie should bring in the crowds who know they'll enjoy a campy action movie but that others won't find much to like.
"Lots of anachronisms and tongue-in-cheek dialogue establish the spoofy nature of this violent venture," he wrote. "All that’s missing is a genuine sense of wit... Despite its few wry jokes, the script is awfully thin."
Other critics were even less complimentary.
"High-concept pitch or no, the movie doesn’t really work," Roger Moore of the McClatchy-Tribune News Service wrote in a review that appeared in the Seattle Times. "Writer-director Tommy Wirkola focuses on the fights and flings all manner of viscera at the 3D camera as limbs are whacked off and heads and torsos explode. Less attention was paid to the story and the dialogue."
