No spoilers, because this movie may appeal to mouth-breathers who identify with the similarly-afflicted villain in this mess. (I can't call him the antagonist, with a clear conscience).
Briefly, this is a story of an evident imbecile who decides to murder an apparent moron. Since the unfortunate leading actors play similarly unintentionally slow-witted roles, there is absolutely no incentive for the viewer to become invested in the outcome. Some reviewers hoped that the damsel in distress would just get snuffed out already and gotten over with - but I can't pretend to be that concerned for the success of either party.
But that's not all. It gets worse.
The majority of the activity is filmed in the dark. Not just "Hollywood dark", as in a filter placed over the camera lens to indicate that it's dark, but actual darkness. So, congratulations to anyone with the ability to absorb photons more efficiently than the ordinary humans among us. Since many psycho-thrillers are completely dependent on the protagonists making stupid decisions, it may be some sort of a mixed blessing that this one makes no departure from that trusty, rusty, old plot device - and stupid decisions pop up with tedious regularity. Accordingly, the vague movements that are dimly noticeable on the dark screen eventually become unimportant enough for us to give up caring about whatever the heck is supposed to be happening.
I watched this dreck virtually for free on Netflix. In my experience, one has to watch a lot of terrible movies in order to appreciate the better ones, so the time lost on this poorly-written and badly-directed pap is just another lesson. Also, I could easily afford the risk of paying less than one hundred percent of my attention to the frequent, boring interludes, to read up about the movie so that I could put the visible fragments together. Without IMDB and Wikipedia to literally spell it out for me, I would still be in the dark. 'Hush' gets two stars because I watched the entire thing. Single stars are reserved for the unwatchable, thus causing the artificially higher rating that I attribute to this one.
A stupid story and and a poorly made flick.
