My wife is way smarter than me. But while I won't concede that Javed Akhtar is awesome, Shabana Azmi is a goddess, Uttarakhand is better than Nargol or that Bongs are the most talented people on the planet - if she tells me she loved II3: Rubaroo yesterday, I'll admit perhaps there is something there. So while I was bored to tears, I'll try my best to see the glass half full here.
First, II3:R gives us the opportunity to listen to the singers without backup music. This gives you an excellent insight into their tonal quality and ability to hold a tune. There was a contrived game host Mini Mathur played with them early on where she would conjure up a situation and ask the contestants to sing a relevant song. This elicited a groan from me initially but listening to the kids sing was educating.
Second, there was "spontaneous" celebration of Mini Mathur's birthday. And this revealed a rather interesting aspect of her personality because normally a chatterbox, she seemed lost for words without looking like an overwhelmed mess - no sobbing, sniffling or on-demand fainting. Nice! Later her rather amiable husband Kabir Khan showed up - displaying all the energy of a 20W bulb. This is a good thing because he looked laid back enough to complement his partner.
Finally, I have a suggestion: since we are talking reality show here (within the recognized limits of reality these days), why not just take the camera inside the contestants' dorms and make it a half hour reality fest? Perhaps a day in the life of a contestant. Or the evolution of a performance from idea to execution. Or: now that one of you has been kicked out, what happens when you get back to the dorms? Who knows - I might even watch without annoying my wife with fake snores.
