I just watched this movie online because I love watching movies about the "Old New York City" before gentrification and this one is definitely one of the funniest that I've seen.
The movie's about this kid from Pennsylvania who's life really isn't all that bad(which I think kind of undermines the movie's premise), but decides to runaway from home because he just doesn't like his step dad who makes does such horrible things like, making him watch his younger brother, while his parents get a much deserved night out.
So, after disobeying his parents and not watching his 3 year old brother, leaving the baby in it's crib by itself, and going to a rock concert, he gets in trouble, and overhears his parents say that life would be "easier without him" while eavesdropping on their conversation and decides to just leave his relatively comfortable suburban existence and go live in Time Square in New York City.
It's there he runs into child molesters and falls in with a drug gang called The Leopards, which is the least intimidating sounding gang of all-time. Even worse, the main gang member is the gay Black dude from "Revenge of the Nerds", who's playing some sort of street smart tough with some some of jewelry wrapped around his head.
The leader of the gang is the terribly miscast Howard Rollins who plays some sort of slick drug kingpin, who uses children to sell drugs for him because they won't get much jail time.
Ultimately, these types of movies usually end up the same eventually, but this one's good for a laugh at the ridiculousness of the '80s and for the landscape of a bygone era in Old New York.
