Recently I watched the English movie " Paranormal Activity". I understand that the movie has been shot with a shoe-string budget. No recognizable actors. No superb cinematography. But the effect the movie creates on the viewer is terrific. The fear that we all have, at least most of us have, for entities that are not human has been well-exploited. I do not remember to have seen any thriller or horror movie in which suggestion that something sinister is about to happen is used so effectively. There are two endings in the DVD. I do not know which ending the movie screened in cinema halls has. But the DVD gives you a choice. Though both the endings are tragic, one is more dramatic while the other is slightly less stomach-churning. I strongly recommend that you see the movie. But there is a strong possibility that if you see the movie late night, then the hours following the end of the movie will see you sleepless, avoiding looking directly at every shadow that appears on the window glass of your bed room .
