I appreciate what u r trying to say and your concern. What sathi re's writer showed was hardcore reality. We live in modern city where this kind of things won't be happen. That's why we feel bad. But in rular part, this is still happen and they called it as .tradition or "rivaj" . so they are not passing a wrong message but are closed to reality.
Regarding suman's study part, again they show reality. Still in some community, girl's marriage is more important than her study. This is happen with my college friend where she wanted to study but her parents wanted to get her married because of "good rishta they got for their girl" and she got married inspite of being a scholar student.
You r right that tv is supposed to be the media not only entertain but educate people. But now a days who cares for it. Everybody wants their trps. I MUST SAY SATHI RE IS VERY NICE AND CLEAN SERIAL. If you watch ekta's serial, they are the most antisocial serial where 3 marriage of a single person, husband having an physical relationship with wife's sister, negative hight of a vamp, etc. there are so many in the list. But don't want to waste my time on it. AND TRAGEDY IS STAR CREATIVE HEADS ARE AFTER SATHI RE SERIAL. WHY IS IT BECAUSE ITS NICE AND CLEAN?
