Season 1 was crazy fun. Rakhi Sawant with her Jezzus! and Ravi Kishan with his Zindagi jhandwa would always represent the quintessential Bigg Boss contestants.. Rupali Ganguli the OG rotlu..
Season 4 was already fun with the tasks and the extremely narcissistic antiques of Veena Malik. But then OG super villain Dolly Bindra entered and completely elevated Shweta and Sameer's game.
Season 7 was very entertaining too. I loved Gau - Andy and Arman Kohli was the OG Shukla and Tanisha the OG Shukli.. Just because of Arman Kohli's bullying I rallied behind Gau. And then Sonakshi Sinha, Hiroo 'aunty' et al got involved and twitter trends and SM entered. It was so much fun.
Season 11 was too much fun too.. All of the contestants had something to contribute. The VG-SS rivalry was one track, and then Hina, Dadlaani, and Arshi had their own tracks. It was hilarious that season. So entertaining.
It's the contestants basically, sometimes they click and sometimes it's just forced.
