I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
There might be a catch-22 at work here: the DC fans probably know enough not to recap more, but I don't. I know a little bit about Green Lantern, but not much about the corps. I didn't really know about some of the characters like Guy Gardener, and John Stewart, and the introductions to them felt pretty vague for a newcomer. Then again, comics only give you so many pages to work with - I've found it's between nineteen and twenty two normally, although this has a nice 25 according to Comixology - so there isn't all that much time to get everyone introduced. There was something explaining the Corps at the back, but there were two issues: it was too small for me to read, and it really didn't help me as I didn't know about it before reading the comic, and it would have been more help at the front.
That being said, I really like what was done with Guy. I know that I've said that it's nice that DC had more archetypal characters in the past, and in a way, I mourn the loss of some of that archetype-ness to create characters a little more like in Marvel. See, Guy was in a coma for a year, he was bitter, he still had panic attacks, and it just made me feel for the guy. But that archetype shine lost a little of its shine. It's a shame in a way, because Marvel and DC were nice counterpart companies: wanted the more humanized characters - in that they had a lot of weaknesses/weren't so much archetypes - and you had Marvel. Liked the mythical, archetypal characters? Well, you had DC. Nowadays, the companies feel a little less different.
The good thing, at least for me, is that it tends to the Marvelization of the spectrum and I end up liking more of DCs stuff. (And yes, I also like dark and gritty and it feels like DC is doing more of that, and I like that, too.)
Okay, enough rambling. The truth is that I liked the characters, I liked the writing, but this is not a great place to start for a beginner. There's no real way to fit in everything they need to know about the characters in here, especially when there's three of the main ones floating around so far.
Still, loved this enough to keep reading. I think I may have enough straight to enjoy the second issue more. Although not until I go see some stupid whales* with my amazing family.
*I really want to read comics on my computer. The whales aren't stupid, I'm just like why can't keep reading?
