I hated it. I don't believe there is a more perfect example in the history of film of hype over substance. I recall going to the cinema and when filing in, everyone was actually a little nervous as they had heard of people fainting when it was released in the US. My brother even advised me not to go in case it traumatised me, as it had been reported in the papers as the scariest film ever made - one even ran a campaign to have it banned.
At the end of the film as the credits rolled, normally people will get up and start to leave. No-one did. Not one person in over 300 in the auditorium could believe it was over. They were all still waiting for the terrifying scares that were promised. When leaving, listening to others comments, almost everyone was of the same opinion, it wasn't scary, it wasn't creepy, and at just 80 minutes they felt short-changed. It was just an all round terrible film.
