Most loved - difficult one as people are more vocal about the people they hate (expect from the obvious fans). I guess Hrithik seems to be quite neutral and he gained lots of sympathy during Kangana gate.
Most hated - definitely not Ranveer (despite the usual Ranbir fanatics), he receives more love than hate on here. I would say it’s a tie between Alia and Deepika. Maybe Ash too. Don’t count Kangana.
