A powerful film which explores the dangers inherent in adultery and untreated mental illness. The director is obviously gifted and creates a vivid atmosphere of tension and fear. The cast is outstanding and each member gives a superb performance. The script is intelligent while at the same time offering a horrific glimpse into an insane night. As the story progresses, it is impossible not to think that appropriate mental health interventions should have been taken at some point. Such an effort might well have prevented much of the suffering depicted. However, this film serves to impress upon the public that such treatment should be sought but it fails in not demonstrating the availability of the required help. The theme of adultery could successfully be dealt with quite effectively through couple's counseling and the establishment of more effective lines of communication between partners. Once again, the film doesn't offer any possible solutions but it does do well to point out the tragic consequences of not confronting the issues involved.

Lots of ideas being bandied about, but I'm pretty sure I get what's happened. Major spoilerage, though, so don't read if you haven't already seen the movie - but might.That said... I'd wager that everyone was already dead at the beginning of the movie. The couple were ghosts who didn't realize they were already dead, thus the girl whispering, "Don't open it" in her sleep near the beginning of the movie and then again at the end just before revealing her corpse. After panning across her corpse at the end, you could see that the chain was hanging off the door - it was already unlocked. That's the way the door was near the beginning, when Alex first opened the door to let David in - he noticed the door had already been unlocked and the chain hanging there, and had to go back into his apartment to retrieve the key so he could lock it again.David, too, was already a ghost by that point. As was the woman in the apartment upstairs - though I suspect she wasn't one of David's victims, but just another ghost living in the building. It's possible that the playing with the lights _could_ have been the living, who they couldn't see - kind of like in "The Others".That's my guess, at least. Makes more sense (to me) than some of the other speculations I'd seen. I don't see any parallels to "Paranormal Activity" at all, and in fact would say this movie exceeds the PA franchise by a great deal in terms of quality.

I give this movie a 4.5 because at the very least it kept me watching long enough to reassure my "guess" about who the monster(s) really was. I believe David killed his girlfriend Sarah and the demons chasing him were his own guilt manifesting itself.His best-friend fell into his hallucinations only as a best friend could.In the last ten minutes of the movie his best friend's girl begins to realize just how insane David's behavior is when she starts resisting to give into the mass hysteria slowly trying to take over the lot of them by refusing to turn out the light.It was a little annoying for obvious reasons(after reading David's journal neither his best friend or his girlfriend's reaction was believable.....at this point you really have to questions David's sanity just a little more as he is hanging around their house looking like strung out drug addict).Also the best friend and David are running around in most of the movie with knives in the dark so I expected someone to at least get a nick a little earlier on.In closing they show David's best-friend's girlfriend laying on the hallway floor(you can tell by the distinctive tile where she is),with a bloody gut wound. Quite obvious to me it was inflicted by David as she wrestled him to escape.In panic mode I don't believe she knew how mortally wounded she was and kept going until she made it to the hallway and then passed away.I enjoyed this movie because it took very little effort to figure out but still had some "jumpy" parts. I do feel the whole movie/story could have been done as a short and would have been much more effective.

I really don't know where to begin here. It was billed as being similar to Paranormal Activity, but the only parallels were the demon theme and the fact that it looked like it was filmed by a 12 year old with a cam corder. They never bother to tell you whats going on or whats terrorizing these people or why. All we know is that there are some creatures that look like Walgreens Halloween costumes wreaking havoc. While I am not the biggest fan of those low budget "documentry? horror movies like Blair Witch and Paranormal Activity, I understand the effectively low budget effect, but David O'Reilly fails miserably to achieve said effect. It is closer to Drag Me to Hell with the person being relentlessly pursued by a demon(s) but without the character development or any of the wit or back story, which is sorely lacks.
