I am going to give this 3 stars, purely and simply because I haven't seen it. Let me see however, if I can summarise the plot.
Women good, Men bad!
That is the basic idea I'm sure. All great actresses in their own right but having to deal with lazy writing with a formulaic plot
Main villain will be some rich bloke who is trying to take over the world or destroy it. Any guys (the very few) who are portrayed in a positive light will be killed off early, to provide a reason to fight and then turn out not to have been killed after all and just be the betrayer. All other males will be misogynistic, sexist or retarded.
Women will be able to majestically beat up proper fighters twice their size, seemingly without effort. All live happily ever after and women save the world.
For those that have seen it, how did I do?
