I sure hope they do something different with this show. I think it is high time Indian TV did finite series or "Seasons" like the West dose. That way actors can stay fresh and so does the story and the audience. Actors can shoot for 6 months and then the next 6 months they are free to do what they wish.
I think it is a good way of stopping burn out and keeping to the spirit of a story. Lets hope Mahakhumb is a pioneer in this. 120 Episodes and if they come back, it will be with a new Season! I have seen the premier episode and it was very impressive.
