These two were the worst judges in II3. Alisha was completely clueless about how the contestant performed. She had no idea if someone was singing on key or off. Her contribution was worse than zero.
Udit on the other hand lacks the personality to be a judge. He went overboard being polite and his analysis was superficial.
Kailash Kher (a very, very talented and trained singer) along with Sonali Bendre will be good replacements. Sonali will focus on presentation while Kailash can focus on technical aspects.
Besides...it's always a pleasure to see Sonali's radiant smile and compelling eyes.
Don't you think?
