Very disappointing movie
30 June 2015 | by See all my reviews

This is the first review of a movie I've ever written and I wouldn't usually do this, but felt the need to advise people to steer clear of this movie. It was truly one of the worst movies that I've ever seen in my life. I had high hopes for the movie before seeing it, especially since I'm a fan of Keanu Reeves in many of his other movies. However I found the movie to be utterly bizarre and ridiculous and struggled to sit through the whole movie and resist the urge to leave. The acting was really over the top at times and so painful to watch. The plot did have potential and could have been so much better but unfortunately it did not work at all in this movie. Many of the scenes are extremely creepy and perverted, and not what I would expect to see in any movie. I found parts of this movie very difficult to understand and follow, so that I eventually lost interest completely. The ending was one of the biggest disappointments and left me with feelings of relief that it was finally over and feeling like I'd just wasted the last 90 minutes of my life. Avoid this movie at all costs!!
