Hard to answer as everyone's tastes differ, but it is VERY unique among those superhero shows. It goes to an extremely surreal place quite regularly, but can range from dark to very sweet and poignant.
Ironically, although I love the show for its faithfulness to the Morrison/Case run, its treatment of Larry Trainor probably owes the least to the source material but provides some of my favourite moments in S1.
Seriously, it’s a great show, although if you’re expecting actual superheroics, they’re fairly thin on the ground.
