I doubt I know all of them, but the three films of street gang genre which came out in the very late 70's and very early 80's were "The Warriors"; "The Outsiders" and this one, "Defiance". Each one had it's own positive and negative points, in my opinion. I have to admit that I've watched "The Warriors" several times over the years, and I never tire of it. On the other hand, one viewing of "The Outsiders" was enough for me, it just didn't hold up. "Defiance" however is an excellent film from start to finish, and I'll be sure to watch it again and again. The film does an outstanding job of showing the essence of what it was like to exist in a then gang-ridden neighborhood in NYC. And there is story behind it, as well as good acting, a touch of a love affair, and most importantly the grittiness of people who are determined to regain what was once theirs, only to be snatched by a gang of merciless thugs. Cheers!
