If Jasmin enters again, I think Colors should let go of the voting system all together. Whats the point, if you are continuously saving your favourites through twists, or bringing them back, if they get eliminated. And these favourites and so-called Colors faces gave such boring content, that they had to bring in challengers. Maybe creatives can just eliminate contestants as they want and bring them back in (which they have been doing this whole season). Something similar to Spilsvilla (because in that show, majorly Roadies contestants win/go to finale, and here Colors faces will win)
I recently started watching again and that was solely because of Rakhi, Arshi, and to some extent Vikas. I have watched Bigg Boss sporadically over the years, and some rivalries and love angles (Gauhar-Tanishaa season), the love angle and the rivalries between couple worked. But its not going to work every time, especially with cringeworthy couples like Eijaz-Pavitra (Siddharth-Shehnaaz in the last season).
Currently, only based on content, I think my top 2 would be Rakhi and Arshi. Not only they have spiced things up, they sort of are carrying the show on their shoulders. Rakhi and Arshi might go OTT at times, and sometimes Arshi is simply intolerable (needs to reign in her expectations and jealousy), but on the whole, they have done so much better in few weeks compared to original contestants. I really hope these two go far and maybe even win the show.
