For some unknown reason, I never can get tired of this series. Frankly I don't really care who wins or loses (unless total crap like Sandeep Acharya beats someone like Karunya).
My guess is that I enjoy the auditions because one gets to see all kinds of sperms that made it to the egg....
Another powerful reason is that it is eye-opening to see a lot of kids from humble backgrounds vie with each other. I bet it would be ripe material to write a thesis if I were a sociology student.
