They are coming up with gimmicks to prolong the show, by having wild card entries (which has now become a regular feature in all the reality shows) but always working towards a seemingly pre-conceived winner.
1. Initially they had a singer being eliminated from the champions side but none from the challengers side, and they thought the challengers had an undue advantage not facing elimination and suddenly decided to have a challenger and a champion eliminated. This situation was something that they could have visualized before...and shows they had absolutely no direction when they decided to start this show.
2. Then they had a wild-card entry and brought in two very good singers Rex and Amey but they never got a chance to make it to the champions side even though they were good..'cos of the format. They had just 2 episodes to prove their worth and I guess we can't complain too much about it as Rex and Amey also knew the score beforehand...but yes, because of alleged manipulations by singers in champions side and challengers side, deserving singers never made it/or made it late to the champions side.
3. Then judge Farah, openly criticized Himani over and over again about her alleged manipulation.... that even though Himani is a very good singer and deserved to be in the champions side much earlier, her stay in the show was limited and exit was guaranteed, thanks to Farah's manipulation. At the end of the day, it was a mind game that Farah played that ensured the Himani would be thrown out, since she planted a seed of doubt about Himani's credibility in the voters mind.
4. They then played the wild-card format for all those champions that exited from the show, but forgot to include Aishwarya! The same Aishwarya was heaped praises galore from all the judges and he was conveniently left out...whereas Prajakta, who is no doubt a very good singer was a given a chance time and again to stay in the show...no matter how her performance was, whereas others never even got a chance!
All these points out to the fact that when they began the show, the concept and handling was not researched into or thought out, but they already had some fixed ideas about who the finalists should be and everybody is playing out towards that end...
The unfortunate ones who suffer is music, the singers (Aishwarya, Himani, Amey, Rex, Toshi to name a few), who are talented and deserve a chance, but are made scapegoats in the fight for channel supremacy and viewership.
