A former general (Ben Kingsley) is wanted by the international community for war crimes. He is being protected by his supporters. He gets moved again and gets new maid Tanja (Hera Hilmar). He is suspicious of the young maid who isn't good at cleaning or cooking.
This is following the wrong protagonist. Sure, Kingsley is the biggest actor here or most anywhere. That instinct only goes so far. He should not be the subject of the movie. Nobody cares if he lives or dies or captured. There is no tension without the rooting interest. Any possible rooting interest resides with Tanja. She should be the protagonist. The mystery of her intentions can be maintain and the reveal would actually mean something. The audience should be invested with her instead of him. The ending should have been shocking but it's met with a shrug and a meh. The idea of making this monster human could be compelling but it needs the context of the war. Without it, nobody can truly get a feel for him.
