^ Twilight makes me want to internally bleed.
First of all, it looks like you're an INTP, not INFP. As for this topic, I agree with the OP's thoughts. The same logic could probably be applied to each type's preference in books, and also movies.
No, I'm INFP, if you're talking about the little graph in my signature, they tend to make F questions too mushy, my F and T scores have always been close though.
Gabriel Garcia Marquez is INFJ? But he has a great variety of characters, they may just be repetitions of the same set of characters based on what traits he emphasized into several different 'categories' or 'distinct personalities'.
Ernest Hemingway is ... ESTP? But he focuses on one main character at a time?
It is not definitive and the distinctions above may be simplistic, but if you look deeper into the authors and their books, I don't doubt there are strong correlations between their types and their created characters, themes and styles.
Actually, I was going to write a literary thing with personality theories about Haruki Murakami's books, if anyone else is a fan.
I thought Murakami is INTP because his main male characters seem very INTX, obsessed with NF female characters and having rare and unique connections with them while lost in a SJ world. But overall, his themes and emotions expressed in his stories point to INFP. But, he is so calm and collected and cool, like NTs.
