I have a confession: For me, that genre is superhero comics. Several of my friends are really into Marvel and such, which I think is great -- they really enjoy that scene, and I'm happy for them. But my attempts to enjoy superhero comics have been less than successful.
For example, I tried the new Ms. Marvel series and was impressed, but I didn't love it as much as I'd hoped to. Kamala Khan is a great and complex character, the artwork is beautiful, and I appreciated exploring the cultural issues within the comics, but the series didn't touch me on a deeper level.
SQUIRREL GIRL IS THE BEST. What really drew me in is the series' laughs and lightheartedness. Squirrel Girl (aka Doreen Green) has a quirky, absurdist, silly sense of humor that makes me feel good, and she doesn't take herself too seriously. Plus, she's smart, creative, and empathetic, which makes her a great role model for young comic book fans. These comics fit me perfectly. I'm so glad I gave this series a try -- it showed me that there are comic books out there for everyone, even people who aren't huge superhero fans.
So let my experience be a lesson to all of you teacher and parents out there. If a kid doesn't like a particular type of literature, it might just be because s/he hasn't found the right book yet. So keep looking and encouraging your students/kids to try different genres and formats.
Also, ultimately, it's OK to not particularly like a genre, and kids need to know that as well. In life, we're not going to like everything we read, and even if we love one poetry/graphica/nonfiction/etc. book doesn't mean we're going to like ALL poetry/graphica/nonfiction/etc. But it's still good to expand your mind with different styles of literature, even if they don't rock your world.
TL;DR version: Keep reading!
