Anyways! I had a slog of a time with this when I started to realize this with every movie, show and book. "Alright, they got their milestone and in 3, 2, 1, kick in the balls to the protagonist (things get worser-er). And then in 3, 2, 1, Chekhov's [object/wisdom] helps them out of the problem..." Then I went to a friend's grill party during this woe-is-me phase. Basic American outdoor party. Hamburgers, hot dogs, chips, soda, beer, etc. Nothing surprising, yet, still enjoyable. Maybe this is more of a philosophical, Buddhist, enlightenment change in perception or just me over analyzing, but... who the fuck cares? No, seriously, who the fuck cares about things being completely different every single damn time? Sure, I like variety in food. Fish, salads, chilis, soups, pierogi, curries, sushi etc. But when you really think about it, there's a level of expectations even when you eat "variety". A level of, "not surprises" I and like 90+% of people out there demand in food. 10-20% surprise is okay, but I have to be in the mood for something completely different. Yes, that looks different to everyone. Everyone has different expectations. But you still expect certain things because you like it. This weird demand that everything is different, every time, is really weird.
Beating to the punch: No, you are not Andrew Zimmern. There's a 99.9% chance you're in denial that you like eating a small subset of food on a regular basis. Nothing wrong with trying and appreciating new, I do it too. But new happens extremely rarely with 99.9% of the population. You don't eat new anywhere as often as you may imagine. My point is, don't pretend you don't enjoy eating the same foods you've enjoyed hundreds of times before.
The same thing goes in stories. There are elements and methods those elements are brought together that I enjoy, just like food. Once I learned to enjoy the things that I actually enjoy in stories, I think my love of books and movies skyrocketed. Doesn't mean I think other genres/subgenres are bad. I just learned, "That's good, but it's not for me and that's okay". I like scifi settings more than fantasy. I used to think I had to like fantasy. Thus, I always chased the "new" to fantasy or I thought it was "derivative". Honestly, if someone ever says a story is derivative, it's code for, "I don't like this genre, setting or general intent of this story. Thus, I'm going to get on my high horse and speak down to this." There's a reason some people can watch all 20+ seasons of Law and Order, but others can't watch more than 1 episode. Or read all cozy mysteries and love them all while others read one and go, "Yea, you read one, you read them all". Which is true. You read 1, maybe 2 different cozy mysteries... they're all the same. But you can also say the same about scifi, fantasy, political thrillers, horror, etc. If you didn't like what it's generally about to begin with, you're probably not going to like it anyways. Other than breakout pieces, this is the truth to story telling. You gravitate to aspects of a story. Settings, character types, plot types, certain themes, etc. Learn what those are and enjoy those. Nothing wrong with hating "popular" or "classics" because they don't speak to you. If it doesn't, it doesn't. Oh well. Find your own pond and build your own cabin. Then enjoy it.
