ITT: Comic adaptations that are actually good.
Nosferatu by Ken Holewczynski and Rafael Nieves is great if you're a fan of the original film. But don't read the colour version.
Two Brothers by Gabriel Ba and Fabio Moon (it's an adaptation of the Portuguese-language novel Dois Irmãos by Milton Hatoum)
Wolf Children: Ame & Yuki is a great companion graphic novel to the Wolf Children animated film, and reading it actually makes the film make more sense, as it expands on the character motivations that seemed to get short shrift in the film's third act.
The Fafhrd and the Gray Mouser adaptations by Chaykin, Mignola, and Al Williamson.
King Conan: The Phoenix on the Sword by Tim Truman and Tomas Giorello (an adaptation of Robert E. Howard's "The Phoenix on the Sword").
I actually enjoy P. Craig Russell's graphic novel adaptation of Gaiman's Coraline novel than the more popular animated film.
