Sacrifice is part of making choices, and making choices drives drama, and drama is the foundation of story. So I guess we should get used to characters making sacrifices.
That said, pointless sacrifice or cliched sacrifice are evidence of poor writing, in my opinion, and we should not try to get used to that.
I was just recently rewatching the movie of "Peyton Place," and it's actually a pretty hard drama, in its stilted 1950s soap opera way. But still I got up and walked out of the tv room to go do my own writing when it got up to the point where a character who had just suffered a reputation-destroying personal trauma was gearing up -- you could see it in the actress's body language, and anyway I'd seen it before, and scenes just like it countless times -- to nobly sacrificing her only chance for happiness with her one true love, the guy who could have taken her away from all the Peyton Place bullshit, who could have healed her wounds, blah, blah, blah, but she wouldn't do that to him because now she was damaged goods who could only drag him down with her, blah. I was just, like, ugh, gods, give me a break. "Why are there no crusty old women in Peyton Place?" I asked my mom. "You know, women who have had 13 kids and outlived 4 husbands, who can tell these idiot girls that, no, seriously, honey, he won't be able to tell. Just marry him and move to a city. Why are there are no old women in this suburb? Do they eat them when they get chewy enough?" And then I walked out, remembering why I never liked that story.
