'Guru' is a certainly manipulative film, and its love story is regular. But still, whatever your taste may be, you should watch it.
And then, Guru of Mani Ratnam starring Abhishek Bachchan works both as a heavy account and a moving biopic of the leading industrialist of the times, Shri Dheerubhai Ambani, and as a saga of turbulent emotions. This film constitutes of brilliant lighting, amazing performances delivered by Abhishek Bachchan and Aishwarya Rai and pitch-perfect textures of dramatic storytelling. The story doesn't shy away from exploring the industrious darkness of Gujarat and the flying culture there. But actually, watch it as a biopic which you haven't seen in so many years.
