I agree with you Gul messed up the story royally! She has done this before, so I am not surprised. Their Ph has a PhD in "going off track and losing focus". I didnt watch IB for 3 months coz it was a Gul show, coz I know what she does. But the Brothers and their stylish appeal made me try it out.
Your right. Even with some glitches the show was on track till the forced wedding. The drama element of the episodes were good. But the sentiments behind it were not. I felt they butchered ShiVika to do this track and I dont think this was the right way to do it. Even a "deal marriage" could have been shown, but it did not have to play out the way this one did. I think if the show had stayed balanced this Spin off would not have happened. But the show lost the plot, and it was not about 3 Bros anymore, it was more about Vamps and then Saas Bahu stuff with Tinky now.
Therefore under the circumstances this decision was made by the channel to do a spin off to focus on the other two guys, and sadly there was no other way around it! If not those guys would probably have left the show eventually. So this is a better outcome any day.
