Abrupt endings

Even if I don’t like a show, I always want a show to have a proper ending and closure. Even if there are loopholes left or whatnot, I still expect a happy ending of some sort because viewers who invested their time on the show deserve that kind of ending. I never really got invested in Durga and lots of things in that show put me off but it’s kind of shocking that it ended just like that. At least it got some sort of closure that Durga won’t have to live with the royal family and her future is secured. But her love story is incomplete and she didn’t find her mom. But compared to Kundali Bhagya ending, this one was much better. The worst ending imo was from Sanjog on Zee TV. About the daughters getting switched at birth and then the FL just dies. It was shocking af because what kind of ending was that?? So even if I don’t like a show (Durga and KB), I always wish for endings that aren’t abrupt. It feels like a waste when you invest time in a show and then they wrap it up without much conclusion. What shows’ abrupt endings had you guys pissed?
