It's Brian K. Vaughn. I never really found his stories that good, Y the Last Man was okay, people put him in high regard, but he's another Joss Whedon type. His stories lack a certain omph! He also wrote a really cringy comic after Trump won about Canada resisting a US invasion of Canada which was terrible. I would say worse than Calexit. Saga is from what I remember mediocre shock spreads like a dragon sucking itself off and SEX! The basic premise is that a moon and a planet have been at war for ages, some guy is caught sleeping with the enemy and they run away because really surface level politics. Again this guy is another Joss Whedon and from Toronto or something, he's more insufferable if I try to remember what he wrote.
