"...No women, No kids..."
A good flic.
One thing that irked me though, was the scene where Leon is "training" Natalie Portmans character in the art of assasination.
One of the exercises was sniping from a rooftop at an otherwise random wealthy/important man jogging in Central Park with his protection detail. IIRC the rifle looked to be something in the AR family, and she shot the man with some kind of empty tranquilizer dart as "practice". Other than being frightened, and stuck with the dart's needle, the target was unhurt.
Any dart that large and heavier than a rifle bullet, shot from a rooftop with sufficient velocity to reach a running man who was at minimum across the street at the park, and probably further, and also 20 stories down, would have been just as lethal as a bullet.
I know the point of the movie was not realisim, but it bugged me the same anyway.
