The good news is that this movie is immeasurably better than Taken 3.
Liam did a good job with his role, as did Ed Harris. Joel Kinnaman, who played Mike (Liam’s son), didn’t have much to work with. His character was consistently expressionless throughout the movie. My guess is that was due to the script and/or director.
The story was okay. The plot isn’t tricky so it’s easy to follow and understand the character’s motivations. My major beef with the story is the reaction of Ed Harris’ character to the death of his son. That seemed to be manufactured just to make the story work and not authentic at all based on his relationship with Liam’s character.
My favorite thing about the movie is the cinematography. They used a neat trick of pulling away from one scene and in one camera shot flying across the city to another location to transition to the next scene. That provided a great sense of continuity in both time and space.
