    You couldn't ask for a better setting for a horror movie. What you could ask for is a better script.

    The final illuminations (people have demons, a mind is a terrible thing to lose) are a poor return on nearly two hours of ear-buckling, eye-stabbing incoherence.

    Little more than an overworked exercise in jostling red herrings, and not particularly fresh herrings at that.

    Nice to see a horror flick with set pieces you don't see coming from miles away... This movie does have its cons, such as the plodding plot development and overly modest soundtrack, but once the credits are rolling, you'll know you just finished watching a scary movie. The ending does a nice job tying together the plot points that the rest of the movie deliberately underexposes. Great effort, must-see for jaded horror fans. Not too long on replay value though, what with the slow pace and the reliance on the surprise ending. Full Review »

    A very average horror film. Some genuinely unsettling and creepy sequences, but for the most part a dry and uninteresting flick. The setting and atmosphere is very spooky and well done, but this is wasted with a bad script and plot-line, and wooden acting. Full Review »

    There came a point in the movie that made it very easy to guess the ending. Despite this it is hard to deny that Session 9 is a smartly crafted thriller/horror flick. A genuinely creepy movie. Full Review »
