I watched this movie alone and at midnight and I got REALLY SCARED!!! I didn't even finish the movie because I felt like someone was watching me... After turning off my PC, I was lying face down because I didn't want to see my surroundings... I was so afraid that I wasn't able to sleep...
This movie is not really sophisticated when it comes to effects and not excellent when it comes to the script, but it will scare the hell out of you.
I enjoyed watching it, but after that the horror begun. I am still afraid to stay home alone... :|
I must admit that things like evil demons, exorcists and ghosts scare me a little bit to much... at least for my age... :)
