*spoilers*
I like Mike Flanagan's work. This movie was okay the first time around when I watched it a few years ago. I just watched it again, and there are so many things in it that make you go, "really??" Her house has so many double glass doors, and several windows. When the man first makes himself known, there are several minutes before he cuts the power, that Maddie could have easily gotten back on her laptop to call a friend. Thus making it a 15 minute movie.
Nothing is stopping this guy from throwing a rock through a window, or door, particularly, easily making his way inside. When she attempts to set off her car alarm with the fob, those things generally work up to 20 feet away.. but oh so coincidentally enough she has to open the door to outside to get it to activate. At first, when her friend approaches the one set of double glass doors trying to get Maddie to notice her and help her, we later see that these were the only locked doors. As Maddie discovers the man has her phone, the other 2 sets of double doors are unlocked. Her friend simply went to the wrong set of doors lol. Had she tried the double doors to her left, she would have made it inside. The man gets a hammer impaled through his forearm. He now has the hammer, yet doesn't use it to make his way inside. Not to mention, no person with her disability would live in such a secluded environment, farthest away from any help or civilization. And someone with her disability would have some sort of emergency contact button or option on her laptop and/phone, if not, 911 doesn't require a network connection, in the event you lose power and lose access to internet. You can dial 911 no matter what. And if someone in jeans and a hoody pretended to be police, I surely wouldn't be dumb enough to not ask to see a badge, let alone believe him and hand over my phone. Need I go on?...
