GOOD THING: One hell of a revelation for us Martian Manhunter fans. Not really a surprise at this point, but it is nice to see something in this series being clarified for a change.
BAD THING: On that note, as nice as it is to see the so-called "Hawkworld" explained, it is a bit jarring to find out that it has nothing to do with the original mini-series. What is more, this explanation only seems to muddy the already dirty waters regarding the continuity of Hawkman by suggesting that Thanagarians evolved from dimensionally displaced Earthlings.
The Final Verdict: Slowly but surely, explanations are starting to come forth. They really could have gotten to the point a lot sooner, though.
