If Vikram and Vedha are seen as symbolic representations of the opposite poles of morality at the beginning of the movie, at the end of it, it isn’t hard to see that there is a Vedha in Vikram and a Vikram in Vedha. The idea behind the poster and the naming of the movie as Vikram Vedha (as opposed to Vikram and Vedha) becomes rather clear and cogent.
Movies are not made for mere entertainment. They are political. They are ethical. We need to be sharp, watch carefully, dig deep and go beyond what merely meets the eye to make sense of what we watch. And that is why Muthu is a masterpiece. It is one of a kind and will always remain so.
