Blame it on K.S.Adhiyamaan. The original which he only directed was terrific. For Hindi, he went full on stereotyping Bollywood & stargiri.
For Madhuri those dance numbers were added. Revathy played her role in the original, director relied on her acting talent than gimmicks.
Salman Khan too. Ofcourse Karthik found it a cakewalk in original. Director again went by Salman's stardom. Aishwarya's character well though was same as in original, you can see she was cast coz of Salman. His character was too Bollywoodised. Except for the confrontation scene, everything else was made typical Bollywood.
Shah Rukh Khan.. honestly his casting was perfect to match the supreme Raghuvaran from original. Sadly, again Adhiyamaan gave him the scenes yet also gave certain scenes to undermine his jealousy issue. He made that comical. I am talking about Gale mein laal tie song & entire scenario of Srk imagining Salman & Madhuri dance. that was of poor taste.
And other supporting actors were totally ignored.
That's why HTHS is nowhere near the Tamil original Thotta Chinungi. May be if it was not delayed so much then it would've looked tiny bit better.
