The most memorable movie i have ever seen is the horror movie 'Paranormal Activity'

I watched it for the first time about 5 years ago when i went to the theater with my friends and it has stuck with me ever since.

The movie is subject to an exorcism. The main character, Katie, who has felt insecure since she was 8 years old, has recently begun to record her 24 hours a day because mysterious phenomenon was getting more worse.

Katie and her boyfriend Mika tried to expel an invisible existence from their home. but, Katie was encroached and everybody was dead.

 The film was unforgettable for me because it did not have a happy ending. I expected every movie concludes with the two main characters living happily ever after.

 I remember being suffered from this movie for a few days whenever something fell suddenly and door was closed itself by wind.
