See the blood, revel in the camera work, marvel at the artistry. Then demand your money back.
This sort of film, glorifying in violence is part of the malaise. It's extroadinary isn't it that a film made by the NHS should be so unpleasant in a violent way that even Youtube put it behind a firewall?
The mindset of those who made, directed, paid and commissioned this should be questioned seriously. By all means talk abou the health impact of smoking. But glorify in a man being beaten up by an invisible assailant? The only invisible assailant is the state. The smoker knows that smoking is bad for him.
