I enjoyed the visual effects used to create some hellish creatures and the amusing nods to "The Exorcist" - cranial rotation, even a spooky staircase. But the movie slips in the last act.

What more could a horror fan ask for than a spook-fest that feels pure in its intentions while taking full advantage of every opportunity to scare us silly?
For as long as it forges ahead without explanations, The Unborn works, in its way, as a series of snap-cut gotchas introducing each new contestant in its pageant of cold-sweat set pieces.
Whereas Japanese horror movies have been criticized for not making sense, The Unborn errs on the opposite extreme, coming off all the more ridiculous for over-explaining itself.

What "The Exorcist" might look like if Madonna rewrote it, this silly fright flick finds college student Casey (Odette Yustman) haunted by a Kabbalistic demon.
Los Angeles Times
Mostly, though, the movie is something of a snooze, a gabby PG-13 horror flick whose most shocking image might be the bored look on Gary Oldman's face as he goes through the motions of playing the rabbi in charge of dispatching the film's damnable demon to somewhere over hell's rainbow.
The New York Times
The film teeters so perilously and routinely at the edge of camp, both with some of its casting choices and some unfortunate dialogue (the repeated warning that "Jumby wants to be born now"), that it's hard to know if Mr. Goyer wants to make us howl with fear or laughter.
The Hollywood Reporter
What finally undoes the struggle to maintain suspense is Goyer's dialogue, which is consistently hokey.
Maybe approaching The Unborn as horror is the wrong approach. Perhaps this should be seen as a comedy. It is quite possibly the most egregiously laughable high-profile supernatural tale since Roman Polanski and Johnny Depp impaled themselves on "The Ninth Gate."

What darkness the movie achieves comes solely from the lighting.
