Actually, I can't say I'll enjoy Sriti in Sudha's role again, as she's been soooooo much better as Sandhya. As Sudha, she was always crying her heart out for one reason or another, and while my heart went out to her, I found it hard to do when she kept turning to Deepu & Padma whenever she wanted to be happy after Jyoti was kicked out.
But Sandhya - she's shown exactly how monster in-laws are to be treated. Contrast Sudha's grudging respect to Bhairavi w/ Sandhya's openly hostile confrontation w/ Prabhavati the night she learnt about her dad's murder. Granted that the offenses are different, but Sandhya has done everything that Sudha rarely did, and Devika overdid. Even if the show ends, it can only be bettered by newer roles for Sriti, not the old Sudha routine.
