Scarlett Johansson is a very watchable actor not just because of her beauty but she’s always thinking and for the most part her characters either seem a little off or a tad different than who think they are.

She’s good but her character is very under written Johansson coasts on her own presence here. I liked Morgan Freeman, he doesn’t do much but he’s Morgan Freeman and he’s always welcome in any film I watch.
