Beginning was great that turned sour. I love science and pseudoscience and even fictional/story science. Personally, the film focused on tool of contrast, making the experiment seem light and positive, then turning it into dark and eerie. However, that was the only tool for horror. Once it occurred, the scare factor drastically dropped, and the genre of psychological becomes questionable.
The film is not bad. I just wanted more. Something a little more risky and imaginative, just have a scientific system regardless if the science is purely fictional or factual.
