Honestly, I'm a bit disappointed with the film. I gave this a 6, where as the first movie was a 8 or 9.
For me, this film lacked everything the first film had and didn't bring anything new to the table. In the first film, we discover John Wick and we learn why the underworld calls him The Boogeyman, a straight up bad ass. The movie did a great job with the asshole kid, that when he kills the dog and steals the car. You can't help but to feel for John Wick. You become somewhat emotionally tied to him. You root for him, you cheer for him and in the end, you want John Wick to get revenge. Every scene was fresh and intense. This movie was fun.
As for the second film, it still retains the good action scenes. However, it's the same scene over and over and over and over. Headshot, headshot, leg shot, headshot, scramble with guy, headshot 2 incoming guys, shoot guy you were scrambling with. Rinse and repeat with different environment. And this goes on for the entire movie. The hitman/woman scenes were great, but The Common and supermodel fight were a let down. I was expecting raid boss fight scenes like Mad Dog, Hammer Girl and Baseball Bat Man from The Raid series. Except all I got was a blue balls that left me saying, "WTF, that's it?". I wasn't emotionally tied with John Wick this time around. I already knew he was a badass, nothing was taking from him in this film that made me root for him. The villain didn't really do anything bad to him nor did I really feel he deserved to die as with the teenage douchebag in the first film. Without spoiling it, John Wick decides to go back into the game because there are rules to follow in the dark underworld. However, at the end he breaks them anyways, which leaves me like the Jackie Chan WTF.
Go see the movie if you like the first one. However, it's not as good. Rental imo.
