I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
Um, yes, arguably this is where having read all the comics would help. But then again, the why wasn't as important as the journey and their sudden stowaway. And this is a lot of fun, with the needed continuity explained in a couple panels that furthered the relationships between these characters, and the rest being a new story. It's nice to know I can just jump in when I want, and will make it more likely to buy more of this in the future, even if I am more invested in a couple characters. I'll wait for them to come along and read those.
