First of all, leave the novel out of the picture. It was a tie-in novelization to promote the movie, and it's highly unlikely that Laurents ever consulted on any of its content in the first place, though, considering what he claimed he wanted to do with the 2009 revival (as opposed to what he actually did), someone must have divulged details to him at some point. Treat this based solely on what's in the script.
Based solely on what's in the script, I would argue that "innocent kids of barely high school age suddenly playing a dangerous game" fits the bill way more than "hardened street toughs," or at the very least that it's more a mixture of both.
