This movie is incredible, I can totally see an underground game going on like this. It truly could be considered a cautionary tale in my book. The game of Nerve as described in the movie is truth or dare without the truth. People run around doing dares for cash driven by people hiding behind a keyboard. In real life people are very brave behind a keyboard but if you call them out they back down. It is very similar in this movie. With plot twists a plenty it will definitely test your nerve and put you on the edge of your seats for this action packed ride. This is for a more mature audience and definitely needs the parental, just because they do it in the movies doesn't mean that you should try it in real life.
