A very high degree of partiality, as evidenced by the last episode.Najim sang well. But the partiality of judges is going on in such a manner that it has become detrimental to the success of other contestants .He ended up getting very high marks even after the very noticeable follwing comments by the judges-
M.G.-"The mistake is not justifiable and you are not supposed to do such mistakes",
Didi- "Very glaring mistake"
Sarath - Justified the mistake by making a comment-"Such mistakes are very common so no need of special mentioning"

The tragedy is that the judges' favourite contestants are enjoying all concessions and justifications for their mistakes while the less favourite contestants have to pay heavily for their mistakes.
Being seniors in the field they should encourage all the upcoming singers.
