As you can see, there is a lot of sex, drugs, and as a replacement to rock 'n' roll, violence would be the equivalent alternative. However, this film could not have been made without these surprising, but yet important factors, taking into consideration that the plot is about a hitman that is injected with something known as the "Beijing Cocktail", a Chinese synthetic chemical that slows all your vital organs until your death. And the only way that you can survive? Adrenaline. RUSH.
So, that's what this guy did. Sex. Drugs. Violence. Full blown. But, this is an action movie that is supposed to give YOU the rush too, after you watch it, it's supposed to put the viewer in the place of the main character, played by a great Jason Statham, and make you experience what he does. Okay, I agree, it could have done with a couple less harsh words, but it just wouldn't be as great if it was censored. So, you might as well just sit back, and enjoy it.
