Ensemble Dark Horse: Ian went from being just the drunkard side character to a fan favorite by the end of the series. Sooni and Leena are this as well. Ramu Sood was rather popular too.
Fan-Preferred Couple: Dougie/Leena was pretty much this from the start of the series and it has been made even stronger by a lot of the viewers dislike of Sarah, Dougie's wife.
Ho Yay: Certain UK fans noted that Ralph came off as rather gay, and hoped he'd be attracted to Aafrin.
Ralph and Bhupinder are rather close to each other as well, especially in the scene following Bhupi's attempted suicide.
Some people claim Ramu Sood and Ian's relationship had scents of this.
There is a Ralph/Eugene fanfiction out there for the benefit of slash fans.
Moral Event Horizon: Ralph crosses it big time in the season 1 final episode when he calmly lets Ramu Sood take the blame and be executed for Jaya's murder, despite knowing Sood to be innocent. It's telling that afterwards Aafrin confides to Alice that he should never have trusted him to begin with. Cynthia has crossed this time and time again, but most notably in her dealings with Jaya: when she left the pregnant girl alone in the village to be mistreated by the locals and to keep her away from Ralph. Ironically, both become quite a bit more sympathetic in the second season, and they're both saints compared to Charlie, who crosses it with his abuse of his wife Alice or, if not that, his attempt to have a treason charge hung on Aafrin for getting too familiar with her.
Questionable Casting: The odd casting choice (at least physically) of Nikesh Patel as Aafrin Dalal who is a Parsi. The darker-skinned Nikesh portraying the Parsi Aafrin is odd, as the Parsi people are very fair/white skinned due to their Persian and Iranian descent and do not have darker skin. Made especially strange as it is implied that the Dalal family in the show stuck to their own kind and only married among people of their own community for generations.
The Scrappy: Sarah Raworth is this for a lot of people who watched the show, with comments varying from what her husband was smoking when he married her to wondering if she has some serious mental problem.
Madeline (and to some extent brother Eugene) are not popular. Especially Madeline, who viewers find highly annoying with very little personality.
Aafrin is sometimes this - some viewers find him dull and boring, and as the series progresses, increasingly unlikable due to his choices.
Ships That Pass in the Night: For some reason, Ralph/Leena has a few supporters. Kaiser and Cynthia as well, though both pairs can actually be counted as being a Crack Ship since the former have no interaction as of Season 1 (and Leena does not think highly of Ralph), while the latter would be impossible considering Cynthia's racist views.
Unpopular Popular Character: In-universe, Ian is horribly unpopular with the British but a favorite with audiences.
Ronnie Keen is fairly popular due to rather humorous and (at times) Butt-Monkey disposition.
Leena may not fit in with either the British or Indian world, but is rather well liked among viewers due to her kind nature and sympathetic situation.
