One such badly mangled and partially burned body is that of Hannah Grace (KIRBY JOHNSON), a young woman who -- unbeknownst to anyone there -- actually died three months ago when her father, Grainger (LOUIS HERTHUM), smothered her to death. He did so during an exorcism where priests tried to extract the demon from her, only to have one be killed and another nearly suffering the same fate. But as strange things start happening in the morgue, Megan wonders if what she's seeing is real, a manifestation of her PTSD, or just her imagination run wild.

Playing out somewhat akin to a "greatest horror film hits" amalgamation, this offering features some decent moments of suspense and jump scares scattered throughout. But the filmmakers have lifted so many elements from past horror flicks (an exorcism, a body that creaks and contorts, a bouncing ball that shows up seemingly by itself, motion sensor lights that go off and have to be reactivated, and on and on) that everything starts feeling more recycled than fresh, original or interesting.

And it also has material that simply doesn't make any sense (both in the moment and later in hindsight), while everything ultimately start to unravel during the third act when the stakes have to be raised (and the frights end up progressively diminished).

I've seen worse, but I've also seen far better, and "The Possession of Hannah Grace" doesn't offer up enough get-under-your-skin scares to offset the borrowing and stealing of concepts and scenes from other such flicks. It rates as a 4 out of 10.
