As the title asks, what do you want or look for in a relatable character? Is it the age, personality, morals, struggle, where they came from, or how they see the world? Does the setting make them more relatable? Do you even want a relatable character? What makes them relatable in the first place?
Its not so much about what I like, as what I dont like and turns me off like a light switch.
I get tired of the juvenile comic book hero alpha stud MC. Its not realistic. You can spot an alpha stud a mile off. The prime bad guy would just put a bullet behind his ear and move on. I want a more matured character, a more complex character. If I wanted to read a comic book, I'd buy a comic book.
I hate things obviously "crafted" to appeal to the latest and greatest politically correct thing. I don't mind a female MC, nor a strong opne. But I get tired of the female version of the comic book alpha female. I'm sick of "wonder woman" running around in designer everything, gorgeous as a model, a crack shot with her gfun in her gucci purse and a kung fu expert. Her FBI boss can't function without her advice and hints how to do his job? Please.
not MC always, but I get tired of "dropped in speeches". Either the writer is pandering to whatever is popular this week, or the editors are dropping it in to fulfill board meeting agendas. It killed me from buying books decades ago.
I'm not a chud. I like plenty of what would be considered left wing characters. I'm willing to engage in suspension of disbelief enjoying the movie in my head. But, these things I listed stop the "movie in my head" by being unrealistic. Hell, I used to read Sharon Green's "warrior" fantasy series. A female amazon warrior, in several books. But none of the above problems existed in her books.
my two cents. These things killed the print industry, they did it to themselves. If they would quit it, the readers would come back. Also? The industry has contracted to a small number of high profile HUGE authors. I liked it better when there were gobs of new and lesser known authors in paperback along the shelves. Lots to pick from, to find little gems.
