Its definitely A One Time Watch Thriller. Bcoz at the second or third time (if it comes to that), the Loopholes will overshadow the entire film!
The basic plot is good. Kate Siegel, with the maximum screentime, is best of the (only) 5 actors.
The (stereotypical horror) set up works to create the ambiece. The protagonist being dumb and mute creates room for an additional attraction & newness..!!
But, the Characters act in silly way. Sometimes, it gets weird & illogically too.
The intention of the Man is unclear as his tactics are. Why he spares time or waits longer to get into the house, why he spends most of the time lingering around the property, why does he unmasks himself in the first 20 minutes of the film ( that makes him rather cool & not scary at all) is best known to him only.
& the climax scene is so Outlandish.. How does the Man land into the bathtub.. Meanwhile she, after stabbing him once, run to the kitchen to damage his eyes with a spray.. may be to attack him in installments.. really seem meaningless!!
*** I was wondering if the Whole Event was the Conclusion part of her New Story.. Something She had fictionalized in her own process.. The Ending part where She was searching for "THE UNPREDICTABLE OPTION" or her Smile at the very last shot all have a Hint to that..!!
Overall, give it a try. It won't disappoint for sure. Hush, despite having all the flaws, will appeal in its own unique way!
