Oof. I really didn't care for this one. Maybe it's because I grew up with a sibling who suffers from schizophrenia and has been told he can "pray it away" or maybe it's the overly descriptive vomit scenes or maybe it's that the writing isn't fantastic but it is more likely a combination of all of these and a plot that didn't do it for me. This is probably trying to say a lot more about how mental illness is vilified in the Catholic Church but it doesn't do so successfully.  I wanted a good spooky possession story but this one wasn't it.
