Horror and Halloween fans-we need your thoughts on this.
A new study has stated Insidious is apparently the scariest Halloween movie of all time.
The study carried out by MattressOnline went through over thirty-four thousand reviews on IMDB.
The main criteria?
How many times the words "nightmare" and "sleep" were mentioned.
The 2010 horror film racked up a score of 206, beating classics like Scream and The Blair Witch Project.
One reviewer commented: "When it scares you both in the theatre, and hours later when you try to sleep at night. Tonight, I will have lots of trouble sleeping.”
The film itself focuses on a couple played by Patrick Wilson and Rose Byrne, as their young son falls into a coma following a paranormal incident in the attic.
