Ice Cream Man

The Ice Cream Man exacts his revenge. Everyone who wronged him is killed: the people who took the witness stand and lied under oath, implicating him in horrific crimes he was innocent of and putting him in prison for something he did not do. The parents die at the hands of their own children. Believing they are attacking a grave containing the villain, the surviving kids accidentally murder and decapitate their own masked parents, including the character Eli Roth plays himself. Jared and Lizzie's parents are among the dead. With the reckoning finished, the Ice Cream Man leaves town, and the children go with him in his wake. The film ends there. It does not say what becomes of them, or whether what he started stops when he goes, which is why we tag the ending ambiguous rather than settled. There is a post-credits sting: one of the decapitated men rides a Segway across the bridge and out of town. It is a gag, not a sequel setup.
