The intrusion genre is not new. And I would not say that this offers too many new things for the viewer. What it does though: it tells the story as good as it gets. And it gives our "villain" the motivation and backstory needed. We kind of expect certain things from a genre entry like this one. And I would say that it fulfills those expectations.

There is moral bankruptcy and there is other things that might rub you the wrong way ... which may work in favor of the movie or not. Depending on how you will be able to process them. Not really surprising, but with an ending that I didn't expect like that either. Really good performances and the movie really takes as much from the story as it is able to.
