Well, I don't get all those harsh critics about the lack of realism, for example regarding the fight scenes, I mean, common, of course a killing machine like Anna is an impossibilty, but does anyone complain about the killing capacities of guys like James Bond, John McClane or John Wick!? Those movies any more realistic!?
Anna is simple a nice entertaining action flick with some good fights, a beautiful and well performing actress, but for certain one of the more conventional and simpler movies made by Mr. Besson. All in all a good movie with some twists and fun moments but no masterpiece.
