"Performing while singing" - Today's approach to Film Singing: Good or Bad?

The approach to playback singing has undergone a drastic change giving more importance to performing while singing. This is the thought i have seeing all the reality shows.
Back to back while shifting channels we observe that reality shows and mega serials have increased in numbers. Am going to stick to the reality shows specific to singing in this post. The competition among the private channels are forcing them to start similar programs by trying to attract more visitors to the respective channels. This idea is acceptable as far as the quality is not compromised and if a bit of creativity is added to make it more interesting.
Performing while singing can be acceptable as far as the people love to do it just the way it comes to them. Otherwise the soul of the song and the performance is getting dropped a bit as they had to concentrate on performing as well. Now, i have seen so many people who sing very well are giving fake performances as they are expected to dance while singing. I think...it is enough for a singer if he/she captures the soul of the song and give their best to do justice to the composition. The contact with the audiences will automatically come as they keep performing. However, when the soul of the song is brought out by the singer...i think...the contact with the audience should automatically work out. If not...it will happen as long as they keep performing in live shows.
When they are in the studio recording for a film song...it is only the feel and soul of the song that matters not the performance. So, ultimately the requirement in playback singing is just the singing, however, performing while singing is the next generation paradigm. A perfect example for singers who did wonders with their voice just by singing are Mrs. S. Janaki, Mrs. Chithra and so many others in the list can be added.
If a singer is comfortable in performing while singing...then it is good that he/she develops that quality, otherwise, as a viewer i feel the contestants are forced to perform and it doesn't look nice on the screen when so many people are watching it. Let them just sing...we can still listen to it if their singing is good. Just for the sake of driving more traffic to their channels, these private TV program organizers are incorporating insane ideas which makes people not to watch the program anymore.
I appreciate the fact that lot of hidden talents are getting recognized through these reality shows, however, i wish that it is more real than reel!
