"For most of this movie, I thought it was quite an interesting situation and it was quite captivating. Then, suddenly, it started an ending that left both my wife and me utterly confused and feeling we'd wasted our time watching the film. It seems that the movie makers couldn't tell the difference between reality and hallucinations any more than the apparent patients could."
"True suspense and mystery throughout. I didn't know what to expect from this movie, and assumed it would be a bit boring, but I was wrong. I was on the edge of my seat most of the movie. It has an unexpected ending with many twists and turns. Definitely worth watching."
