Re: The fight on the stairs
It seems the fight scene is done in one shot from the top of the stairs all the way until the get halfway through the car ride. But it's total deception. There were at least 7 scene changes that I could count. I like scenes like this, but I hate the deception involved in making such scenes. Either do it truthfully, or let it go. They treat the audience like we're dumb or something.
I enjoyed to movie and the complexity of the story, but a woman whipping up on multiple trained thugs is just a little unbelievable.
