Went into this expecting straight horror but was a bit surprised, much more suspense/drama than I was expecting. Really feel like this is the opposite of Enter The Void, where I would've rather had another 15 minutes added on to it to flesh it out more, horror seems to do better with shorter runtimes but this one seemed like it was over before it really had time to shine.
The last second of the movie was also something. Went to take a drink of water right as it was ending and whoopsie daisy down the wrong pipe, have fun coughing for the next two to three minutes.
