Try Destroyer MAX. It's a fun (and bloody) romp in 6 issues. That was my first experience with Kirkman, I liked it so I started Invincible right after that and I'm still in love with it.
I also liked his Ant Man miniseries, but a lot of people dislike it because the main character (not Hank or Scott, a new Ant Man, Eric) is a huge jerk with very few redeeming qualities. Still, it's fun.
