Forty-five years after The Exorcist, we can still count the number of legitimately great demonic-possession movies on the fingers of one hand. (And that's including works that employ the conceit only tangentially, as this past summer's phenomenal Hereditary does.) Consequently, in regard to this particular horror-flick sub-genre, it's easy to be grateful for the little things, and Dutch director Diederik Van Rooijen's The Possession of Hannah Grace, although fair-to-middling overall, actually boasts a number of little things worthy of gratitude. It's doubtful you'll remember much about the film a day after seeing it, but while you're there, it's an inoffensive way to pass 85 low-expectation minutes.
