great post, u've said pretty much everything, actually. i also think the ph rushed the show a bit and not everything was perfectly in its place, so execution has suffered. maybe they wanted to jump in ahead of ipl, but they didn't give themselves enough time to get the show established.
but sanaya and supriya r doing a great job as r most of the supporting cast so they r not the issue. unfortunately the ml is the weakest link but what to do? and yeah, trp audience expect a tight script, layered characterisation, a bit of drama/tension and better execution, other than that i think the show has all the potential to do well!
i like that sanaya chose something different, she has to explore her potential as an actress and try different genres. i'm hoping the ph is giving it till the end of ipl and by then will have worked out the kinks in the show and will present to the audience what they originally narrated to sanaya 😛
