While the acting and the gore are good, everything else (storyline, script characters) is just underdeveloped, lazy and predictable (i.e. not scary). All the main characters doing all the stupid things they KNOW they aren't supposed to do, and being short-sighted, hysterical jerks makes them quite unlikable.
Also, a little framework to statements like "god and the church are dead" or "evil likes children and children like evil" would have been nice.
All in all, it's a wasted hour and fourty minutes of my life that I'm never getting back.
