Aeon Flux
The plot: Aeon is a resistance fighter fighting against the Goodchild Dynasty - a totalitarian state which seems to provide harmony for it's people in the last remaining human city on Earth, but of course all is not that rosey.The good: Charlize Theron, plot isn't totally predictable.
The bad: While the plot isn't predictable it is very, very generic.
Conclusion: Enjoyable movie, don't go expecting to see anything new but go expecting to see something entertaining.
