I was thinking about this if. If "Archie" comic's can get gritty and "Power Rangers" can get gritty this will also work. Here is how you do it. Kevin is now a adult and in prision because after the events of the first two films social services finally took him away from his parents. After years growing up in brutal foster homes he turned to crime and eventually landed in prision. Along the way he had child with a prositute.
After 5 years in prision he gets out and decides to look up the prositute because she also stole some money from him and he wants it back. Turns out she is living in a abanded crack house. He goes there to get it only to find out his son is there all by himself. The movie will be about the kid trying to keep him from breaking in, because he wants to find the money that was stolen, and the kid will use all sorts of funny over the top "Evil Dead " style violence to keep stoping him at ever turn.
