For those who aren’t a fan of cartoons, Invincible could be your converter, up there with other adult cartoons like BoJack Horseman and Rick and Morty. Based on a comic book from Robert Kirkman, the creator of the Walking Dead, Invincible follows 17-year-old Mark Grayson and his training to become a superhero just like his father, who happens to be the most powerful superhero on the planet. Episodes run long at nearly 50 minutes, connected into one big, blood-spattered story. A subversive series with a huge cast featuring Steven Yeun, Sandra Oh and J.K. Simmons, Invincible will engross you in its smart animated world.
