When Anubhav Sinha must've thought of remaking Nick Cassavetes' Hollywood film John Q. [2002; Denzel Washington], his intentions were extremely noble. The story of a father, who could cross all limits to save the life of his child, can strike a chord with any person living in India or Timbuktu.
But the problem with Tathastu is that it comes too late in the day. Meaning, as viewers, we've already witnessed innumerable movies on roughly the same subject, of a man's lone fight against the system. Only the issue keeps changing in film after film.
Nothing wrong if a concept is repeated by a storyteller. After all, every craftsman has his way of interpreting a story. But Tathastu is a sound idea with noble intentions that goes awry because of a poorly crafted screenplay [writers: Yash-Vinay] and mediocre direction.
