Starts out mysterious and creepy and concludes with a nifty, direct connection with the first Conjuring movie. Sadly, along the way, the writers give into horror cliches and undermine what could have been an above average prequel: people needlessly separating from each other to wander alone down dark, evil passages; a heroine who screams approximately seven times too often; and, that desperate refuge of weak horror scripts, zombified corpse ghost revanent demon things. Writing this to get to the required 600. How long did it take a committee to come up with that random number? Okay I need four more, there that did it.
