Patrick, a while ago I recommended to you Southern Comfort, which you enjoyed. I suggest you take SC up on his advice and check out The Warriors, which is also directed by Walter Hill. The violence is dated by today's standards, but it's a compelling flick all the same; sort of like Southern Comfort in New York at night.

In the same year, Philip Kaufman directed a similar (though in my opinion inferior) film called The Warriors, which I also recommend.

Boyz N the Hood is great.
