The problem with the movie is that it is boring.
No intrigue. He wanted to sell weapons and started selling them. He wanted a beautiful girl, she seduced him. The agent caught him, but did not catch him. So what? What's the point for the viewer?
Boring dialogue in the style of "never fight yourself."
But what I didn't like most was that the characters didn't fit the image of arms dealers. I haven’t seen one in real life, but this actor is more like the failed director he played in another movie. Always with a suffering expression, turns away when they shoot. How could he become a gun dealer?
