Disclaimer- I've only watched bits and pieces of the serial so far.
The thing is that Ankit's character is not really what you'd expect from a ITV hero, more so because he slept with Tejo and then ditched her for her own sister. That I suppose is the really irredeemable part for many watchers, especially because Tejo's character is written as a bit of a mahaan one. If he hadn't crossed that line, many folks would probably still be fine with Fateh as a character, and with Fatejo being the end game.
He's not negative, but not very hero-ish either. Can't root for him, but not so bad that you simply root against him either.
Somewhat grey, and you'd say folks like this exist IRL.
Atleast he does get to poke fun at his own character- in today's episode, Jasmine asks him if the TejAng engagement isn't "ajeeb" and he replies saying "I divorced Tejo and am going to marry her own sister, what can be more ajeeb than this!" 😃
If polygny was legal in India, Fateh's character would've happily married both sisters!
On the plus side, the serial is comfortably Rangu's best on the TRP chart and Ankit is raking in a fair bit of moolah, and I suppose that's all what matters at the end of the day!
