Extremely creepy and the final payoff is really disturbing. Kept my interest for most of it mostly because the janitor is played so well.

This terribly unsettling film shows again that true horror is not about showing gore, it's about psychology. During the film, you often wonder how bad a person can be... only to watch the boundaries broken again. Tosar is fantastic as the janitor and rightly collected a number of Spanish film awards, and he and director Balagueró are certainly worth following.

Absolutely wonderful creep-fest. The anti-protagonist thinks himself a Hannibal Lecter, and his adversary unwittingly "fights" back with nothing more than the strength of her charactrer. This is a movie Hitchcock would be proud of...if he were a much creepier dude. Outstanding!

Tosar is an effective lead and the concept is interesting/creepy, but there isn't a lot hiding under the surface. A few suspenseful moments, but weak resolutions.

i haven't got the slightest clue why he did all of these things. i mean what's the point of showing the mother if you won't link her situation to the main matter. was it a red herring or a gap in scenario? who knows...

Besides some loose ends and a weak finale this is definitely something to watch.

Balagueró is one of the most interesting up-and-coming horror directors working today. It hasn't led to another sleepless night, but I was definitely biting my nails in suspense at the wonderful natural interplay of events on screen, providing the film with an atmosphere so subtly overwhelming it was almost tangible. Too bad this isn't maintained in its misguided soap opera-ish 3rd act. Still worth seeking out for sense of dread is inspires, Tosar's performance and the sweet cinematography.

"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." - Ed Gonzalez

Kompletnie sie tego nie spodziewalem - znakomity thriller. W swoim gatunku zdecydowanie wybija sie ponad przecietnosc.

This isn't anywhere near as scary as [Rec] or To Let, but I actually appreciate Balagueró's readiness to use a more subdued, even reserved script. The villain in Sleep Tight is not a cold-blooded, fearless, superhumanly strong or sneaky psychopath, as one has come to expect from this type of thriller. The sense that he is a twisted, but "real person", often on the brink of miserable failure, makes his sinister exploits a lot more intriguing.

Went in knowing absolutely nothing about this movie. Was seriously confused for the first 15 minutes...and then boom. You can't spell Spain without 'pain.'

Mean-spirited psychological thriller with an effective central performance and some tense scenes.
