Good beginning, then becomes frustrating A heroine movie where the lead character is the lead because she is the victim. And a victim of what, we will never know. It is implied that her husband is a monster, while she is completely innocent. Even at the end, we still had no evidence on the husband, other than his general creepy attitude. Nothing within the movie showed us that he ever did anything wrong. All the while, she's incoherently bumbling around, milking her sob story and pity party.
It is assumed he was stalking her, but why, I don't know other than he desperately wants to have a baby with a woman who hates his guts. In addition, there's no backstory to make us hate him.
Also,we never get any information about this "suit", other than he must be some rich, closet, crazy genius, who invests millions into his man cave.
Ultimately, she goes nuts for an hour and goes game of thrones on him, then walks away with a sadistic smile. She's the scary one, and it's plain to see. Why did he marry her, and what was her job again? That's right, she's the good one and he's the bad guy, and she walks away with murder. Contrived and disappointing it is.
