Old story in new cinema.
This is the fourth movie that A Harsha has repeated his Bhajarangi storyline - Vajrakaaya, Jai Maruthi 800, Seetharama kalyana and now B2. With movies like Baahubali, Magadheera and our own Kavaludhaari showing how costumes and sets can be linked to a particular period in time, this movie has costumes from all of human kind and should be a case study for evolution of mankind. If you have watched Bhajarangi, you will feel a sense of deja Vu everywhere including Shivanna's green eye lens showing when hero gets his power from original and killed Bhajarangi.
I expected a lot of realism in Ayurveda and diseases, but it remained in the teaser and nothing here. Time KFI learnt to make realistic and quality movies.
