Jenna Walter The film may be flawed, but its message is not.

Erica Derrick By the time the dramatic fireworks start popping off, each one feels earned.

Guillelmina The film's masterful storytelling did its job. The message was clear. No need to overdo.

Cissy Évelyne It really made me laugh, but for some moments I was tearing up because I could relate so much.

stevedye1868 By the time i had gotten far enough into the movie to "give it a go" i was far too invested in it to give up (or maybe just too lazy to spend time looking for something else to watch). As has been said, the movie mainly focuses on one guy's emotional downwards spiral and how it is affecting his two friends. The ending? well that was just a cop out. There was no real finale as such. It was like buying a huge firework that has this long fuse that, when the fuse reaches the firework and you are expecting this huge display of sound and light and all you get is "pufft". Oh, and, although it is titled "The Possession of David O'Reilly" i didn't actually see any scene where David O'Reilly was ever actually possessed at all. It was more about a poor guy going crazy and trying to keep something, that may or may not have been a figment of his imagination, out of his friends house. Now, the thing is, it could have been really quite good, the groundwork was all sound. But, unfortunately for the viewers, it was as though the screenplay writer/s were on a deadline and didn't have time to work out a real plot for the end. There are a few jumpy scenes and parts where you are led into the start of a good story, but thats where it stops. It's no "Blair Witch" or "Paranormal Activity"...but, quite easily could have been with a little more thought and what was there was quite well done. Really let down, mainly, by the poor ending 4/10

sempremilanista I have seen this movie twice now just to make sure I had a decent understanding of it. It starts out interesting but very soon takes a weird and dark turn. This movie kind of reminds me of certain Spanish movies where the outcome is just all kinds of bad. Lots of anxiety, creepy lighting, and sadness, and no glimpse of hope. Depression and a quite precarious sense of being accompanies this film, and the lighting and setting doesn't help. Creepy glass and dim lamps pair with the sad and oppressive theme. To its credit, certain scenes are for sure creepy and "jumpy" like the ones with the "demons" appearing outside, but for me anyway, the jumpiness of the lead character and his manic crap made me nervous and just took away the fun of an otherwise good horror flick.

freddy54-211-469054 I have seen this film twice and after the second viewing, I came to the conclusion that although flawed, the film does contain several unsettling scenes. Overall, I think it is a study of the mental disintegration of the central character, David. How this is achieved is partly through the inclusion of some of the most gruesomely imagined monsters ever to appear on screen. The fact that we only see them briefly and often in half-light is a bonus. By the end of the film, I understood that all four characters are going through a groundhog day experience, from which there is no escape. This is what makes the film very disturbing, leaving a rather bitter aftertaste. We need more British horror movies like this, which show an imagination that no American director could hope to achieve without sacrificing credibility. I would also include "Salvage", "The Disappeared", "13 Hours" and "Outpost".

Samuel Pointer I was so frustrated whilst watching this. The potential for a fantastic film was all there but it was all let down by the lack of info and the obscure plot.At first I was lead to believe that this was going to be a new improved British version of Paranormal Activity... I was wrong.I was dieing for this film to break forward and become its own film. But instead I was just left wondering WHY!? Why? Why did this happen? Why does that happen? At one point I though a few questions were going to be answered as to why this demon is doing this haunting and this was hinted at but still not made clear. With abstract shots of small dark rooms we're led on a cryptic path where nothing is really explained as to why or how it's happening.
