On second thoughts there are many heroines of 80's like Shobhana, Urvashi, Nadiya Moidu, Meena, Revathi etc who can make a good pairing with superstars.
But difference between Shobhana and others is that Shobhana is more active in dance and she is not active in films. So this comeback becomes special. Meena thadi vachu aa oru pazhaya charm poyi. But still she has managed to remain as heroine itself in films like Drishyam and Munthirivalli . Urvashi sadly is getting only character roles now. Nadhiya too does character roles in other language films though she still gets heroine roles in Malayalam. Revathy would have made a good pair with Lal ettan but sadly WCC issues like 'Enne nadi ennu vilichu' ennokke.
So Shobhana is still having a star value now. But she should be selective as she is now. Else she will end up like Shanti Krishna who made a good comeback with Njandu but now doing insignificant roles like in Vijay Super and KBO films
