So, I went and saw The Exorcism of Emily Rose last night. As a horror movie, I have to rate it "A Big Bucket o' Suck". It wasn't scary. Not even mildly. The total amount of time they spend dealing with the actual exorcism and the scary demon bits is about 5 minutes. Seriously.
The rest of the time is spent dealing with the court case surrounding the trial of the priest who performed the exorcism. As a courtroom drama or an examination of the spiritual realm, this movie was ok. But the geniuses in marketing decided to advertise this as a horror movie. Which it is not.
So, to summorize, if you like scary movies, don't bother seeing The Exorcism of Emily Rose. If you are very, very easily scared, you might like this movie. Of course, if you're that easily scared, save your ten bucks and just go around at other things that probably scare you, like cans of tuna or those novelty foam cowboy hats.
