How does a 7 year old, innocent schoolchild know the specifics of crimes which transpired 25 years ago? Has someone been feeding him these stories? Does his dead father communicate with him? Why does a man wearing a 'batman' like mask befriend the boy? Malayalam movie #Nizhal is supposed to be a whodunit, but the slow pace is a downer. Running time should be reduced by 20 minutes. Cinematography n performances r good. Rating 2.5/5.
