This movie is essentially about a serial killer. The opening scene is of Denzel, as a NYC police officer, wondering into a crime scene. He looks around and has some loose industrial equipment fall on him. He spends the rest of the movie in bed, unable to walk. This introduces Queen Latifah, who plays his bedside nurse.
The first time you see Angelina, she's hustling out of some guys apartment late for work. As soon as I saw that, I knew what was going to happen next. The guy comes out of the bathroom wearing just a towel and begins explaining to Angelina that he needs more. What guy who's just casually fucking Angelina Jolie would say that? A little liberal gender role reversal. See, women can be just as casual about sex as men can (heres a hint: NO THEY CAN'T).
You see the serial killer abduct people, but you never actually see his face until the end. The killings are usually not shown. He did use a steam pipe to burn a woman to death. Not sure I wanted to see that anyways.
I'll just skip to the grande finale. Turns out the technician who works on the medical equipment Denzel uses to stay alive is actually the killer. He was a cop too, but years before Denzel had exposed that he was a corrupt cop and got him thrown in the slammer. The killer briefly talked about being repeatedly raped in the showers. Angelina shows up at the last second to shoot him in the back.
Righteous Kill, the Lethal Weapons, etc. You have the lead cop who bends the rules, because he's gotta do what he's gotta do to catch the bad guys. Lots of internal squabbling with the Captain, who needs everyone to be in their place (played by Michael Rooker in this one). Internal Affairs is snooping around and they're treated like pariahs by the rest of the department. Lots of tension between the rookies and the veterans. The only problem with this non sense is that if you watch any of the cop reality tv shows, First 48, you'll see its like a regular office job. Detectives just sit around waiting for hot tips. I could write a better cop script, if the pencil was in my ass.
