MY GOD!!! I sat thru 132 mins of nothing!!! The cliffhanger ending of part 3 was for nothing as this has the same presenter, crew and medium but is about a house in London being haunted, or so they say? Nothing happens again but this is even worse, its just repetitive and dull!!! Where's the 'Demons' of the title??? We had a Eastern European psychic woman reading coffee bean in a 40 year old cup for nearly half an hour!!!! Shots of fake ghost reading gadgets spelling out words, people asking ghosts stupid questions abd axreally annoying radio scanning machine that was just a acge for my ears, urgh! If ur doing a fake ghost hunting show for over 2 hrs at least have something happen.
