Had some merits, but suffered from bad writing, and a pretty boring 1st half. Things do pick up in the 2nd half, but the horror scenes seem to draw a very fine line between being interesting and unintentionally funny. I burst out laughing a couple times.
Many of the performances really didn't seem to gel with me. The cast is super talented, especially Jake Gyllenhaal, so I feel like it may be in the directing and the material they had to work with.
