What are some things that always make shows/books/movies great? What attracts you to new shows? Whether certain character types, or plots, or maybe certain writing or filming, what makes your favorite media good to you?
I'm a believer of if something is done well then it doesn't have to be new.
Taken and John Wick weren't new ideas and the plot is a checklist of events that even have chase sequences in the final act, but because they were well directed and had well written characters, the movies felt fresh and exciting. Some goes for TV shows, just do the damn things well.
For books I like attention to detail and a good degree of heartfelt depth, I need a writer to care about what they're writing. I can usually tell when writers don't care and it really puts me off their work.
I agree with the other posts about having good characters and interesting worlds.
I don't even have to like the character as person, sometimes I find having unreliable or morally imperfect characters to follow even more interesting. Can I understand where these character's are coming from and why they have their motivations? Did the world that these characters are in shape their viewpoints? Those questions interest me and get me engrossed.
I also really like ambiguity and the ability for stories to leave gray areas that leaves things up to interpretation. I get tired when a story always tells me exactly how every little thing works out, why it does, etc., I'd rather be able to think about it my own way. Letting the viewer/reader ponder events and some undefined areas makes them feel more involved. I'm not talking about fan-fiction or anything, that's something separate that I'm not personally as invested in, but I don't need filler, and I don't need everything laid out neatly for me. It's sort of like when songs are interpreted in multiple ways; I'm sure writers have a general idea for what they're going for, but I enjoy when they sort of sit back and let other people view it in different ways, as long as it isn't harmful.
the thing i look most for in a story is that i feel like i've grown in some way for having read it. I'd say the most common way a story does this for me is by introducing me to new perspectives. I like to see characters that think or act in ways i haven't seen before, or put into unique situations. Philosophical stories are also good.
Good plotting/cohesive narrative with few plot holes.
Good conflict and character motivations.
All of the above four things are executed using the unique nature of the medium that the story's being told through. If it's writing, the prose just makes it easier to read, if it's film, shot composition, editing, lighting, and so forth, if it's a video game, the narrative fuels the gameplay, and the gameplay makes the game fun, and if it's an anime, good animation.
At least, that's how I judge a story, and they're not all in particular order, but they're all necessary.
