Mainstream critics have pretty thouroughly panned it: Atlanta Journal-Constitution
Bob Longino "It's as enjoyable as acid reflux." New York Post Lou Lumenick "...by far the year's worst movie, a most dubious achievement." Lumenick went on to chracterize the movie as "moronic and incoherent," which I found far from true. Genre and on-line critics were somewhat more kind. There is actual plot, and I found the convolutions entertaining if not always original, although there were some genuine surprises.
Being an MTV co-production, you know Style is going to be a major factor in design, and indeed there is plenty of that, and it is well done. All of Aeon's outfits are de rigeur sexy, and Theron manages to carry them off without looking ridiculous, unlike Halle Berry in "Catwoman," (whith which this film is being unjustly compared, in my opinion). There is a nice unified design to the film from the clothing to the institutional Brutalist architecture throughout the city.
Since the plot involves armed resistance, assassinations, and coup and counter-coups, there is indeed lots of fighting and shooting, but very little gore. Nifty high-tech spy gadgetry abounds. What sex there is is suggested only. I would say, quite entertaining for adults if you like the occasional action-adventure.
