Main problem with big boss is that after completing 12 seasons successfully without shukla, shuklis and shuklapur, they think they can't survive without him in future. If they think this season is dull and flop without giving freshers any chance, this won't be first flop season, there are many. After not so interesting season 9&10, they got blockbuster season 11. After totally dull season 12, they got successful seasons 13. No need to throw ex contestants on freshers. You can't win jackpot everytime.
Only reason I admire Asim and Rashami, they dare to challange unhygienic colors ka beta/damad who was protected beyond a limit. He and his shuklis were beyond pathetic, specifically that piece of nonsense 'mai na, woh na' Shehaaz. When you think that is done and dusted, we got him as senior citizens and we have more shuklis with bigger chuglis.
