When you've spent a long time watching a specific TV series and getting invested in the characters, it's SO DISAPPOINTING when one of your favorites doesn't get the ending they deserve.
For example, Penny spent the entire last season of The Big Bang Theory dealing with the realization that she didn't want kids, only to be pregnant in the finale just to serve Sheldon's character arc.
Or, how, at the end of Killing Eve, Villanelle finally beat the bad guys and seemed like she was going to end up with Eve...only to get shot out of nowhere right before the final credits rolled.
Or, how How I Met Your Mother built up the importance of Tracy (the mother) for nine seasons, only to end the show by killing her off so that Ted could end up with Robin.
