Public Voting in Reality Shows - Boon or Bane?

As the jungs between contestants in our favourite musical reality shows are growing nearer, we, as the viewers, are clinging onto our seats, in utter anxiousness to see if our winner will come to the end. How can we assure that our favourite will make it to the top? Well, if you've got no mobile or cell phone, you're pretty much out of luck. For years together now, the basis of voting in music shows have been us, the janta. We make the final decision of who wins the title and who doesn't - but is this fair?Tears fall from our eyes when we see our favourite contesants get eliminated from a show and lose their chance of becoming India's next voice. This gives the incentive for viewers to not blame themselves, but rather, the channel. Whose fault is this?Channel heads will blame it on the public voters - after all, it's use who send hundreds of SMS messages everyday to keep our favourites at the top, but when we see them go, who do we blame? The last resort is to blame the format of the musical reality shows, where this question arises - should we continue to have public voting as the final decision maker for the shows? If talented contestants are getting ousted out each week, then should the judges have the final say in who goes and who stays? What should be the actual format for these shows?We cannot decide ourselves, but we can surely think. Is public voting the way to go? Are we able to trust our janta to the fullest and make sure that talent wins over everything else, or must the judges and other important factors be forced to play a key role as well?
