Well done but hurt by the familiarity of possession / exorcism and the inevitable comparison to The Exorcist. Also hurt by the moving-into-a-house-where-bad-things-happened cliché, which gives the viewers an explanation for what they’re seeing. The Exorcist offers no such rationale – what happened to that little girl was beyond reason, and therefore (at least to me) far more disturbing and frightening.
