This move is just a long shootout, with enough setup to know the characters and what’s going on. It keeps you guessing initially about when the fight will start, and for the most part the action is pretty cool. It sticks to a more gritty realism tone than many other movies of this genre, but that only makes the more unbelievable aspects jarring when they come up. And instead of weaving the narrative into a cohesive surprise turn or diatribe against gun running, it basically just ends.
Closest comparison: It’s like the shootouts from The Salton Sea without the context of story or a satisfying ending.
