Looking at Mike Mignola's work. For the longest time I didn't like his art. I never really gave it a chance, not until the Hellboy movie with Perlman, whom I'm a huge fan of. After seeing the movie, I gave the comics a chance, and became familiar with Mike's work. And now I love his art, it's more complex than it seems. And it frustrates me when others don't appreciate it.
When I saw The Amazing Screw On Head, I thought, 'How can his art possibly translate to animation well?' However, I LOVED it. It is criminal it wasn't made into a series, but the world IS insane after all. Madness happens every second.
