Across regional movies, to my limited span of knowledge, i hardly remember any movie which has knowledge has the key element of the movie – while there are few movies which I can think of, the theme is either around family drama or around some supernatural forces.
Eeeram(2009) is one such movie. The hero is a police, who is investigating the unnatural death of his ex-girlfriend. During that process, he gets the knowledge about the unnatural death through the supernatural force (his ex-girlfriend’s spirit if you believe in life after death!) – which comes in the form of water – while it was a fresh breath for the Tamil cinema, it had its regular mix of romance and family drama. It is one of those brilliant plots from a new comer director Arivazhagan and Shankar (the famous director of Rajnikanth’s Robot movie) is the producer.
