My review of the Blackest Night tie-in, R.E.B.E.L.S. #10 is up at popsyndicate.com:
I haven't been keeping up with DC's "cosmic" titles since 52, but since I was picking up a copy of R.E.B.E.L.S. in my quest to get all of the promotional lantern rings DC is distributing with various Blackest Night tie-in titles. My familiarity with this title is limited, though I had read L.E.G.I.O.N. back in the day because I was a fan of the event it had initially spun out of (Invasion!), I was unaware of what took them from being a "legion" to being "rebels". Though that information was not forthcoming, the issue itself was a good introduction to the characters and its overall concepts.
