Don't believe the hype, this movie is NOT good. Firstly, I found the acting wooden and hammy, as was the dialogue. Elizabeth Moss' ptsd act gets tiresome after a while. Now for the plot holes galore.
This technology being worked on, why isn't the government or military hovering over it? When the supposedly abusive husband (we never see a lot of evidence of that) dies, why is all of his advanced tech just sitting untouched in the house? Why is there a dog living in the house and nobody seems to care? The dog's owner had been dead for weeks. Surely there were people going to visit the house to see what was going on. The brother certainly didn't say he moved into the house. Everything was covered with sheets, leading one to believe there wasn't anyone living there, so where does the dog come from?
Why does the dog bark at the 'invisible man'? If he belongs to the pretending-to-be-dead husband, wouldn't he recognize him regardless of the suit?
Fast forward to when Elizabeth Moss' character is in some psychiatric hospital. Her 'invisible man' is supposedly there watching her, but everyone thinks she's crazy. Well, why is he also going into her room and getting locked in there with her every night? Then that fight scene with all the guards was ridiculous. Do mental hospitals really have an army of heavily armed guards? And they kept coming in 2's, but could never seem to see this 'invisible man' even though his suit was malfunctioning. Moss certainly didn't try to help by grabbing the nearest gun and shooting at him until all the guards were dead.
Then how does said 'invisible man' get away? Did he drive? Did he call an uber? Somehow these invisible suit men get around without needing a car. They also exhibit super human strength, no explanation.
And what was up with all that rain. It seemed like it was supposed to be an important plot point, by the way the camera focuses on the TV with the news story about the weather. I thought it would have a purpose, but apparently, it was only to have a really wet confrontation in the parking lot that went nowhere. And of course, the rain, which sounded like the storm of the century, magically disappears once you see the cop friend's house lol. That must have been a long trip!
And why would the brother be 'set up' by going to the cop's house? What was the set up? He's just okay with killing random people? And if he was really the killer from the hospital, why wasn't his suit malfunctioning. And speaking of the suit working properly, how was it even powered? The suit looked like it was perfectly fit to the person's body, so where was the battery? Crammed up the butt-crack? lol
Leading to the ending - were there actually three suits? The brother was killed in one suit, Moss hid another suit when she visited the house earlier, so the malfunctioning suit makes three. Assuming that the abusive husband was the one doing all of the killing/stalking. And I guess it's one size fits all suit, because apparently this suit fits everyone perfectly, including the shorter Moss.
Now, this movie is way too complicated for it's own good, kind of like my write-up lol. Half way into the film, I was thinking the good plot twist was that the brother was responsible all along, and that making Moss look crazy would mean her money could go to him. Or something to that effect. Anyway, don't believe the hype. This movie really is clumsy. Wait for it to come on Netflix.
