I have been a fan of Larry Clark's for many years. Unfortunately the quality of his work is inconsistent.
"Kids" was an amazing movie. "Bully" was (in my opinion), terrible. "Wassup Rockers" falls somewhere in between the two, but closer to "Bully."
All other criticisms aside, this movie was a snoozer. A bunch of kids trying to make it home through hostile territory, dodging police, encountering odd-balls, etc., losing a few of their group en route. It was already done in "Warriors" which was a much better movie.
None of the main characters stood out, and all of the people were portrayed as very two-dimensional. The rich people were racists, except for the girls who secretly wanted kids from the other side of the tracks. If you aren't white and rich, don't set foot in Beverly Hills. And so on. Pure stereotypes, but not very good ones.
