Just saw this finally, and if the first was a 10 , this one was a 5. I get the "assassin world fiction" is a big attraction to the plot, but what did it for me in the first one was the over the top revenge story. You fuck with a mans car and dog, mix in the fact he is already pissed about his wife, you have the recipe for a bad ass movie.
This was extremely generic. You lose the driving force behind the first movie. For me the assassin world stuff isn't well done enough to make the movie good, it seemed even John Wick was bored in a couple scenes...like what am I doing and why.
