'Shakuntala Devi' Trailer: While some praise Vidya Balan's acting; many left disappointed

Amazon Prime Video on Wednesday unveiled the trailer of much-awaited biographical drama Shakuntala Devi, starring Vidya Balan in the titular role. Giving us a glimpse into the life of the world-renowned math genius, the trailer has received a rather much-mixed response from the audience.

While many were left in awe at Shakuntala Devi's ability to do incredibly fast calculations (which also gave her the title of "human-computer") others weren't impressed with the trailer.
