I still need to watch the third one. The second one was a drop off from the first, but still good, violent, mindless fun. My favorite aspect of it is how the non-assassin "normal" people just quietly keep walking while killers shoot the hell out of everything around them; sort of like NPCs from a video game. I have expected one of them to tell Wick that he used to be a professional killer, but then he took an arrow to the knee.
