Prachi and Sudha truly didn't deserve to get voted out - participants like Mikka and Sonali are worse dancers than they are!!!! I do agree that they should give everyone a chance who were voted out - but in truth Prachi and Sudha's elimination was the most shocking, because they were the best dancers there.
As far as BT dictating who should be brought back in is stupid, because I have seen articles myself where the aam janta has said that they would like to see Prachi back in the competition. If Balaji had such dominance, than Ronit and Jai would never be in the bottom three constantly and Prachi would never have been voted out.
