A have read a review on this site, where the poster says he or she has seen similar things in other horror films. This may be true but it is pretty hard with poltergeist movies not to duplicate, things being displaced etc, I found the setting of 70's Britain excellent,having lived through the 70's it brought back memories of collars on the outside of jackets and the humour added another dimension. The acting was realistic and unlike so many films there was a story which had a conclusion. How many times do we sit with the credits coming down and think "is that it, has it finished?" Personally I don't believe in ghosts, poltergeists, exorcisms, etc but this film kept me entertained which is all you can ask.
