Sigma movie review: Jason Sanjay’s debut has the vision but not the script to match

Sigma review: Jason Sanjay’s directorial debut has Sundeep Kishan’s energy, Lyca’s budget and the weight of being CM Vijay’s son’s first film. What it does not have is a screenplay that knows what to do with any of it.Sigma movie review and rating: Every heist film makes the same promise to the audience: We are going to show you something you have not seen before.
