What other Neil Gaiman work might you like?
The biggest thing to know about Neil Gaiman is that each work of his is a mixture of horror, fantasy, and subtle comedy.
That being said, each of his projects is pretty distinct from one another and there might be some that are more up to your tastes than others.
I haven't read some of his newer stuff (because I largely stopped reading as much since the early 2010s), but I'll do my best to remember what matters in other works.
Horror
The Sandman is a great work for horror fans. It's also great for mythology fans and other nerds, but horror is a major push and pull factors.
The comic is probably the greatest body of work Gaiman produced and it's recommended if you're a goth at heart and are comfortable with themes of death and humans being gods' toys.
The Sandman (TV) is a great adaptation, but it's very short so far and doesn't cover the best stories.
Coraline is a horror story for children. It doesn't have anything that's not suitable for kids, but it can be viscerally scary to some people. Both the book and the film are great.
Mirrormask is my personal favourite, it's a low budget film with mindblowing surreal imagery and one of the best soundtracks ever.
It's about a teenage girl who has troubles with her parents (who run a circus, btw) and who gets swiped up by her imagination into a bizarre world that is being eaten by her depression. Not a scary film, per se, but it's disturbing. However, it's a very warm film and it always makes me feel better.
Fantasy
Neverwhere is set in a dimension of twisted London Underground where everything that's straightforward in our world becomes weird and too real.
It really tickled my imagination, I highly recommend the book.
Stardust is set in a more high fantasy setting.
It features kings, witches, ghosts, and a star that fell to the Earth. It has a young protagonist who's not exactly the best or the brightest person, so if you hate such things, stick to the adaptation. In my opinion, the book is just lovely.
American Gods is a darker fantasy that asks the questions: "What if every god people ever believed in became real through the power of their worship? And then what if that worship started fading?"
It's set in the USA and because that country is such a melting pot, there are many gods. And not all of them are happy. This is the book that gave Neil Gaiman his reputation of a writer who loves weird sex scenes.
Humour
Stardust the film is often compared to Princess Bride. It's lighthearted, funny, full of imaginative adventures.
Just a very nice film with an all-star cast.
Anansi Boys is a spin off of American Gods, but it's a lot more lighthearted.
Anansi is a trickster god, so you know things will get funky.
I haven't read The Graveyard Book and The Ocean at the End of the Lane yet, but I hear they're very good as well.
Also, short story collections or Norse Mythology might be a good place to start if you want to get a feel of Neil Gaiman as an author first.
