It's interesting, because that kind of split-partnership tension story is something that's actually rather hard for me to read! I completely love that you enjoy it--I just don't usually, myself, and I think it's really fascinating that the kind of plot type that one person really enjoys reading about/viewing, can be just difficult for another person to sit through. It shows just how much of a reader's assessment of stories is personal to them, and not reflective of the merits of the story itself.
Thinking about it, though, my problem might be simply that most of the examples that I've seen of that plot type have been
poorly-written examples. I'm sure you've seen them--the ones with unrealistic character choices, and friends turning on each other for the weakest reasons, so that you sit through the entire thing frustrated at the characters and completely unsympathetic to any of them. I actually do have plans to write a really
good plot where two characters, previously friends, fall out due to an actual tough situation. Similar to the descending-character-arc plot type, where a character undergoes a moral downfall--I've seen that done poorly so many times that I really, really want to write a realistic and satisfying one myself! But meanwhile, every time you see a pair of characters who get along really well in some ongoing TV series or book series, you just know there's going to be that one episode or book where the writers get bored and make them suddenly doubt and seriously distrust each other's motives, despite all their history together. In fact, I'm planning to completely subvert that concept in a future book of the series I'm working on--the bad guys deliberately start a campaign to divide the two main character allies and make them start distrusting each other, but the two of them actually
realize what's going on and decide to stage an entire quarrel and division between them just to trap their enemies.
I think I might be a little bit traumatized, actually.
Every time I see any
good character relationship in any kind of show or book, especially one that's supposed to be a romance, I'm instantly worried the writers are soon going to make them start doubting and hating each other for some completely unnecessary reason. I don't dislike relationships being
tested--I love relationships being tested, in the most horrendous of ways. I just don't enjoy seeing them
fail the test, at least not without really strong reasons.
Again, no judgement at all upon you or anyone else who really likes a good, juicy, partnerships-going-sour plot! I'm sure if I'd exposed myself to more examples that were well-written, I wouldn't have the visceral dislike of it that I do. I even wrote one myself for a 75-worder Challenge last year, which actually ended in murder--I'm still planning to turn that into a full story someday. And interestingly, the Frodo and Sam conflict actually works pretty well for me, since the whole point was that possession of the Ring makes people act out of character, and meanwhile Sam never once wavered in loyalty to his friend. If it weren't for the corrupting/addictive influence of the Ring, though, I'd probably hate it completely, especially since it wasn't even in the book to begin with.
It just...
sometimes, not always, seems like writers think they have to ruin a good thing just for the drama of it, you know?
The worst examples I can think of right now are...let's see, about 3/4 of all Wodehouse plots (actually, now that I think about it, that might be the main source of my trauma!), and old TV shows like Mister Ed and Get Smart which occasionally use the main characters, romantically or no, being
very upset with each other just for gags.
The
best examples I can think of...actually, for me, are the ones where the friendship is never repaired. The "we were friends, once" concept. I love the tragedy of that. I'm pretty sure my brain has mostly sworn off the "misunderstandings as plot points" concept, and when a friendship is falling apart for
actual reasons, yet nothing significant changes about the characters in the end--which would actually make the relationship
stronger than before, rather than simply returning the characters to their original state--then any solution the writer can provide for them to be friends again would be no solution at all. Basically, if you're going to
realistically attack it, the relationship
cannot ever be the same again. It has to change, either for the worse or for the better. The story cannot just go on and pretend it never happened, or that it was all wiped away when the characters choose to forgive, because if the problems were real, then you're solving nothing and going nowhere--and while that obviously happens all the time in real life, it's
not a resolution to your story. Which, of course, could be the whole point of the story, but in most cases it isn't.
Anyway, huge apologies if this approaches the level of a rant no one wanted to hear about, or if this is just the wrong place to talk about it. I
think it's relevant here? I'm truly not rubbishing the concept in any way, I think it's really dramatically powerful,
when done right, and I'm keenly interested in doing it right myself one day, which first of all means exploring examples of what other people have written and, most importantly, deciding what are well-written examples of that kind of story and what aren't. I think the best "we were friends, once" story I've come across so far is probably...actually, I can think of several
good ones, but I can't think of a clear
best one without thinking about it for a few hours, so I'll do that, and come back when I think of one. I've already spent over two hours on this post and I'm way out of free time!
