Sleep Tight, first of all, is a nifty new Euro-horror film, with several wicked-cold Hitchcockian twists, that shows off the range and craft of terrific Spanish director Jaume Balagueró, co-founder of the "[Rec]" franchise (still the gold standard in found-footage horror).
What are people saying?
What are critics saying?
The states get higher with every breadcrumb Luis Tosar's creep lays down, and the film derives sometimes remarkable corkscrew tension from watching him being backed into a corner.
Sleep Tight is a nifty little thriller that dances on the boundary between plausible and preposterous.
The Hollywood Reporter by John DeFore
Jaume Balabueró's effective thriller Sleep Tight puts more value on slow-building bad vibes than on pulled-curtain shock, but its treatment of mental illness and voyeurism, lightly salted with pitch-black humor, will feel pleasingly familiar to fans of the older film.
There's a Polanskian black comedy buried in here somewhere; a sassy neighbor girl who knows too much hints at the right direction, which is never fully explored.

Mr. Balagueró is so overtaken by his villain that he becomes like César, displaying an eagerness to play the role of tormentor, which kills both the movie's pleasure and its flickering political subtext.
Director Jaume Balagueró's film is nothing if not a well-executed bit of escalating craziness.
This is a crime story with little to no interest in the who or the why, but only the what and the how. It's a reverse-procedural, tracking not the solution of a crime, but all of its awful particulars.
Sleep Tight is a creepy - but highly effective and superbly made - horror movie from Spain in which the monster is spine-tinglingly human.
Ultimately, Sleep Tight makes a sounder case for nocturnal Webcams than the "Paranormal Activity" franchise ever could.
