You know the expression "...opening up a can of worms", THIS entire franchise is exactly that. In case you are unaware with how this all began and the story soo far (I could be off as it has been a while, so spoilers if you have not seen any of the John Wick movies especially the first one). John Wick is minding his own business when a guy compliments his car and wants to buy it. After refusing, said car is stolen and John Wicks dog is killed. Not to go into how much the dog means to John but John is an ex-assassin and he seeks revenge on the person who killed his dog. That was Chapter 1. This is Chapter 4.
To say this film does exactly what it says on the tin is an understatement. This film is simply a revenge film which has spiralled soo out of control, we are on the fourth film and it looks epic. There are elements to this which are almost nonsensical, but the world they have built for this movie, is incredible. The close quarters fights. The close quarters fights that include guns. The raw and visceral attacks with any instrument. If this trailer did it for you and you have not seen the previous three movies, I suggest you watch it before this as they all tend to lead on from the one before it and it is soo so good!
