Details in books and written media as a list, not a series of images. Loved reading as a kid, dropped off when I spent more time doing other things, like cpmouter gaming.
The upside is that witthout a mental picture of characters any close enough visual take on the character will work for me. I also have ADHD so small details are likely forgotten and only the prominent ones that the character is defined by are going to be weird if mkssed.
For example when I heard Idris Elba was going to be cast as Roland in The Dark Tower it was a big positive because he seemed like someone that would be able to oull off the personality of the character and I was only concerned about whether they would do a good job with the missing fingers or drop it entirely as missing fingers was a big part of Roland's character for me. Yeah I know there was something involving race in the books, but that plotline was something that didn't seem to be necessary to carry over into a movie.
Of course the movie ended up being a pile of trash, but is a good example of how I focus more on how the character acts than how they look.
Same with a lot of science, swords, and other objects where I really don't have a mental image so a lot of sets work as long as they have the things or the general feel.
