This film is worth watching if you remotely think you can pay respect to Nambi Sir. Nambi sir was there throughout the film making process so he was that much involved in it which makes this film very near to his heart.
Many so called critics who are bought and sold in the market are trying to bring this film down by finding faults in real stories of Nambi sir's life, these are the same critics who declare an average film a hit just because they get paid or its a film of political agenda or star kid is in it.
As this is independent film maker's film and the story dipicts a real mistake of India to torture patriotic scientist which will not be befincial in any way to these selfish critics so they are be "critics"
I would say film is definitely entertaining and along with it, it also tells a true story of a patriot who still is looking for due respect and money.
Please watch this movie in theatres and show support to Nambi Sir, because we all know we won't speak up against the system.
