“Madtown” (** out of four) was an unsatisfying melodrama about an aspiring comic (Milo Ventimiglia) who is haunted by memories of his sister (Amanda Aday) and is confronted by her after she’s released from prison and their numerous childhood secrets come back to haunt and affect both of them. Aptly titled story starts off well but then becomes progressively more weird and flat to the point that it’s hard to care about anything. Both Ventimiglia and Aday’s strong performances are definite plusses and keep you watching
