There’s been a fair bit of buzz building around The Last Exorcism, partly because of the presence of Eli Roth amongst the producers, and also intrigue over whether its mockumentary angle will be able to bring something new to an increasingly stale horror staple. And it really is down to the execution, as the plot is fairly standard stuff about a troubled priest going off into the backwoods to perform his final exorcism, on a girl who’s father is convinced she’s possessed by a demon. However the conceit or having the preacher followed on his mission by a documentary crew certainly promises something a little different, and if the movie is as creepy as the trailer, it could be a winner.
