This is by far the worst film I have ever watched. So boring. The only reason it has good reviews is because the acting is good from Stephen Graham and the "film critics" (who just love to be different and edgy) get all excited because it was filmed in one shot, plain and simple. For the average Joe like me who wants to watch something with a good storyline etc it is beyond terrible. Do not waste 90 minutes of your life watching this, I'd rather stare at the television screen with it being turned off for 90 minutes and that is not an exaggeration. Just dreadful.
I'm 99.9% sure that anyone who has reviewed this 5* didn't actually enjoy it whatsoever. Another one to add to the list where it's cool to think it's good.
