Review of Hostage to the Devil

I knew nothing of this man Malachi Martin when I looked into watching Hostage to the Devil but I enjoy a good exorcism story as much as the next and going into this I believed it to be a straight up movie and not actually a documentary on the gentleman's life. It wasn't actually until I came on IMDB some 20 minutes into the film to check out previous reviews of this documentary to see if this was one of those fake 'spoof' type of affairs and while I I believe this person existed now, throughout the film I still got this air of inauthenticity about it. Perhaps it was because the film was too pro-Malachi and his beliefs to establish a balanced view of the man with just one dissenter who I felt was made out to be a bitter dying man because Martin allegedly started an affair with his wife. It was an absorbing watch however and a curious look at what many 'rational' minded group of people could just have easily labelled Martin as a charismatic con artist.
