Director Karyn Kusama speaks volumes in what appears to be the slowest story I have ever seen. I didn't realize until Act 3, but the slow and personal story being told has a purpose. Logan Marshall-Green's performance was convincing, and ultimately caused me to be lulled into an incorrect prediction of the final act. This is a horror film with no jump scares or horrifying imagery, so not a terrible one to pull out with a queasy friend!
