Quick take: Ustaad Bhagat Singh is a dated masala potboiler salvaged only by Pawan Kalyan's charisma.Can a star's charisma overshadow mediocre writing? At times it does. But on most occasions, that creative gamble doesn't deliver and Pawan Kalyan fans will realise this when thy watch Ustaad Bhagat Singh in theatres this weekend. The film begins with an assassination attempt on the Chief Minister of Telangana, played by KS Ravikumar.
