Hard to ignore some gaping mistakes in the plot:
1. The lead character finds the money, but not the briefcase full of "liquid O" that is right behind it. He finds a box full of cash, but does not look in the ceiling again to see if there is more, or anything else up there?
2. The thugs find the drugs in the apartment after the police have searched the apartment. The police, suspecting that there is a drug tie-in, never think to look in the drop-down ceiling?
3. The couple is about to be evicted, and about to lose "the house." This means the house they are renting? Why not move into the house that he is fixing up and has inherited? It had a roof and walls, and he knows carpentry. No rent to pay if they move into the house, yes?
4. No one seems concerned that a police officer, or someone dressed as a police officer, shot a detective and continued shooting in a public park. Never mentioned on the news they listen to? Never brought up in any of the conversations among the characters?
5. When nailing the thug to the floor, the lead male is somehow able to know exactly where both of his feet were positioned, although the floor is solid where he is standing, with none of the cracks that can be seen in other parts of the floor.
6. The same thug, hiding from people with guns, lights a cigarette, which might not seem wise, since smoke could be seen coming from the room where he is hiding, or smelled. But no one does see or smell it, including Khan, who walks right up to, and almost past, the room before being shot at.
7. No one tries to put out the fire, which is confined to a small section of the house once the shooting has ended.
And of course, the clichés were terrifying--the couple trying to have a child and learning at the end that they were going to have a child. The detective who has lost a child to drugs, and is now seeking to destroy the drug trade? Somehow, the obvious cliché was missed--this couple needed a dog. A dog, wounded in the battle with the drug dealers, but recovered by the end and leaping into their laps after the news that a child is on the way. If you're going to do it badly, go ahead and do it badly.
