Here not sure the argument makes sense, but at least, it would have been interesting to explore. But the film is impossible to take seriously. It’s not just the scrappy making, or the equally scrappy performances. It’s scenes like the one where Arjun, when he develops an interest in Diya, asks her, “Vayasukku vandhuttiya?” (Have you come of age?) Or the scene where she tells him, “Naan sumaarana figure.” (I am no great looker.) Do young people really talk like this? I am not trying to be superior. I am genuinely curious, for in film after film, we are asked to buy this lingo. Or is it just male filmmakers projecting their fantasies onto the big screen? These thoughts gave more to chew on than the movie.
