The first one was the only one worth watching. Story about a man getting vengeance for his dog was great. All the nonsense about some secret hitman underworld didn’t make any sense
I got so bored watching the first movie that I turned it off after like 40 min. The emotional core of the movie is so simplistic (they literally kill his puppy? Are you joking?) and the superficial plot elements with the coins and all the assassins and stuff is so overly complicated… I didn’t think the action scenes were very engaging either. I would much rather watch The Bourne Identity.

This guy went on a rampage that killed dozens and it all started when his girlfriend swatted a fly on him which woke him up. My point is that something small can be the tipping point.
If you didn’t like the action… well, I got nothing.
