Since the forum is empty, I decided to give review on the first episode.
The show actually begins with a sophisticated Bengali family and they introduced all the characters of Kajol's family. All the characters are diversely designed and you can like all of them despite their colour shades. This factor actually makes the show interesting. Since the concept is how a girl becomes a family-woman and takes responsibilities, the diverse characteristics is indeed a good idea. Somehow, they made few things subtle for good.
Regarding Arjun, his introduction was good. Though screen space was less, the makers gave a clear cut view of his character - a rich and sophisticated Casanova. He is in romantic relationship with his Bhabhi and flirts openly with his Saali. Personally I had a laugh when he is behaving shamelessly.
Rahul is not yet introduced. Arjun's family will be introduced in the next episode. They look like a typical rich cameo family.
The good thing about the show is, the characters. I hope all the characters would have own space in the story other than revolving around the leads. Sets looked pretty and Bengali Culture was not stereotyped (as far I know, not sure). So far, nothing negative.
