Upon finding himself under attack by a strange demonic cult, an anthropology professor tries to come to terms with his attitude when dealing with such groups in the past as he struggles to fight off the group's demonic ambushes.Pretty enjoyable effort at times, though this is still pretty flawed. The best parts here are clearly the attempts at reality-altering that occur throughout the film, consisting of numerous visions that seem to occur at random times throughout the story, which range from bloody mutilations to demonic hallucinations and the appearance of real demons that really make this pretty freaky at times since there's a great tendency to use it for both reality and the hallucinations, making it unclear what's really happening. The use of black magic in the finale is pretty fun, and the deaths are plenty gory enough, though this one's problems do rear up. The villain here is a total joke and inspires nothing to fear, the followers are even worse as they look just like punks on adrenaline, and the continued implications that tell us otherwise are tiresome after a while. Plus, there's also the mistake of not doing any explaining of what's going on, leaving this slightly confusing as to what's the point. Though it's still watchable, these were enough to knock it down a little.Rated R: Graphic Language, Graphic Violence, Brief Nudity and a sex scene.

I simply love this movie, not only because it was the first DVD I bought in the year 2001 but also because the idea of the movie is great.When watching the movie, you don't know what's going to happen next. Some movies are quite predictable but this one isn't. There is so much going on with the Dr. Harry Ballard (Karl Urban). The trouble for Harry Ballard starts when he receives a video from Satanists.After that many things are happening and his only hope is the pretty and mysterious Benny. Is she a guardian angel in this dark and mysterious world, or is she just insane? Perhaps she is even something scarier? Harry risk losing everything during his quest for answers because he is about to uncover the truth . . . the irrefutable truth about demons.

Buy two get one free. That's the only reason I bought this movie. The Irrefutable Truth About Demons was the only movie left in the bin that looked remotely interesting. Irony would have it that it turned out way better than the other two movies that I actually paid for. I was expecting a sh*tfest and I was very unexpectedly pleased with this film. I've said it before, that's what can make a good movie great. Karl Urban has a hand in making this a foreign horror gem as well. I recently saw him in the theater...twice; I happened to dig Ghost Ship and you may recognize him from some little movie called The Two Towers or something like that. If this guy keeps grabbing these kinds of roles, he could be one to watch for. The story centers around a cult in Lord of Illusions fashion called The Black Lodge (a Lynch reference?). It's not as great as Lord of Illusions, but it does a good job of keeping you on your toes. You never know what's in store for our hero from one encounter to another. There are quite a few complaints about it being boring, but I don't agree with that at all. It held my attention from first scene to last. And, thankfully, it keeps the CG to a minimum (just a few scenes, and they are awful). The end of the film was reminiscent of The Attic Expeditions in that you're not quite sure you know what's going on. Maybe that's the way it was supposed to be, or maybe they just couldn't think of a better ending. Either way, it's not a problem. My only quibble then, is that in the States, this movie is simply known as The Truth About Demons. I guess America's not ready for big words like "irrefutable."

I watched about 20-30 minutes and to call this one horror, i would not approve... I felt nothing, nothing at all!! All that happens can be predicted, and with good accuracy too!
