4 stars given, but it should probably be more like 3 1/2 (if Goodreads allowed us to do that).
This is a quick read, even at 6 issues, and it's fun mainly because of all of the cosmic characters.
We've got the Earth-based Hawks, we have Shayera (RIP Hawkworld and Katar Hol, personal favorites, but at least we see half of that pairing), we have a couple of Green Lanterns (Kyle and Kilowog), we have Adam Strange, we have L.E.G.I.O.N. (just a little bit), and we have Captain Comet, who I always love to see. If we'd had a certain Daxamite, it would all be there for me.
* See spoiler at bottom for one big gripe
I've never been a fan of this ongoing conceit of having Rann and Thanagar always at war, but at least it lets me see these characters.
That said, the story feels incomplete. This doesn't feel like its own series or miniseries. It plays so directly off of previous events, in fact being directly based on some major ones that are mentioned in passing, and then it ends so inconclusively, that it just isn't quite satisfying as its own story. I feel like you need to collect a good few other books (and not all have been put together into trades) to really get a full story.
Still, it's decently written (nice to see Dave Gibbons handling cosmic characters, only wish there'd been more GLC), the art is gorgeous (not as good as the Adam Strange mini that came before it, but still reminiscent of that level), and it's a fun read.
Find it for cheap and enjoy it with some popcorn.
* SPOILER
The killing of Shayera feels so rushed, and thoroughly unnecessary. It feels almost like there was a mandate to kill of any remaining references to Hawkworld and that part of the Hawks' background, and clear the way for a totally different take on Thanagar, more in line with what we've seen in recent years.
Very disappointing to have a character that some of us came to care for deeply in the 90s and early 2000s killed off so quickly and unneccesarily.
