Let me tell you the difference between Mere Sai and Sai Baba (Star Plus)
This is a nice show on Sai Baba but according to my perception, Ramanand Sagar's Sai Baba which aired on Star Plus was the best. In that serial; the solid cast, the music, the settings, the production values were very high whereas in Mere Sai, the story somewhat doesn't sync according to the Satcharitra. In the Star Plus Sai Baba; even though Sagars took some liberties in adding some extra stories, atleast they showed between 70-80% true main stories from the satcharitra. The main character Sai Baba was played by Mukul Nag in Sai Baba (Star Plus) and Abeer Sufi plays the part in the same character in Mere Sai. Mukul was realistic and outstanding whereas Abeer is good in his own way.
Even though Sagars did skip some scenes in Sai Baba (Star Plus) like Kulkarni-Dwarkanath becoming devotees, Booti building the Krishna temple, Lakshmi getting 9 coins from Baba and Baba's samadhi; the overall serial covered up everything from Satcharitra whereas Mere Sai has until now not showed anything much except Chand Patil getting this horse back in the 2nd episode.
I can therefore conclude that Sai Baba of Star Plus was the best serial and whenever I pray to Baba, the actor who comes in my mind is Mukul Nag.
