Although Farah is not a singer, and people consider only THAT to be the requirements to be an apt judge, I do think that Farah's a good judge in spite of that.! Though she doesn't sing, she choreographs songs and gives them a new meaning, so she does have a good ear, and can pick up people's faults really well.
besides that, I also like how she speaks her mind.! It was unfortunate that Himani got kicked out this week, but you can't only fault Farah for that.! Fault everyone who took part in it -> the champs, Himani and then Farah. The woman just called Himani out on her game-plan.
