What an intriguing comic this is. The characters, the setting, the time travel; it's all just interesting. And I quite like Cliff Chiang's artwork. 
 I went in hesitant about the use of homophobic slurs, which was something I'd seen mentioned in reviews. I understand why Vaughan wrote it that way, and for me, the fact that other characters immediately called out the behavior made it tolerable--but I wish he'd left it out to begin with.
