As someone who has studied this subject from an ISLAMIC POINT OF VIEW, I found this program surprisingly accurate SOMETIMES, according to what some Muslim "Exorcists" have encountered, though there are differences in theological points of view of what one is dealing with and how to deal with it. Beautifully filmed (the seminary is actually now the British Muslim Heritage centre in Manchester, and I happened to visit it one day while they were filming) well acted, MARTIN SHAW IS BRILLIANT IN THIS. So far this has been great. My only quibble with it is the last episode although well written could have shown more accurately how Muslim 'exorcists' deal with this issue. Very wishy washy in that respect, The 'Imam' did nothing right in dealing with the problem and some of the things he said were incorrect according to Muslim theology. I thought though that it was good to show the respect between the Christian and Muslim men, and this is needed more to bring our communities together.
It is also good that a well made programme like this has come out amidst the utter tripe and dangerous nonsense programmes that glorify the occult such as The Charmed et al. This definately doesn't so far. I don't believe anyone should be offended with this from a religious point of view, if anything, some of the lines can be taken to be quite inspiring for people of all faiths, and particularly scenes showing Father Jacob's unswerving faith were quite moving. Although I don't know what the next episodes are going to be like, so far so good. (Episodes 1,2 and 5 the best so far).
